Thanks for the info regarding the closure of Garage 1. That's always been my preferred parking location, so I guess I will need to shift over to Garage 2 as much as possible starting in Jan.
Garage 1 is not being closed, only the pedestrian tunnel that connects it to the terminal. Shuttle buses will service the garage as they have in the past.

The 'best' part about it is that from what I can see there is literally no vision or concept in place on how to fix this issue.
There are several, problem is none of them will solve the issue of reliability and reasonably speedy service.
I have been saying this for more then 20 years, WMATA has a rolling stock shortage. The rolling stock shortage dates back to when the the Huntington station opened on 12 17 1983. They had a rolling stock shortage before the Silver line was opened, it was amplified after the first segment opened to Wiehle-Reston East. It will still exist when all of the 7k car are delivered and rest of the line Silver line opens to Ashburn and the cars slated for retirement are removed from service.

Dulles Corridor Metrorail Project Pictures 01 17 2016
Utility tunneling under the Access / Toll Roads at the Reston Town Center and Herndon stations continues. Tunneling under the Access / Toll Roads for the third rail conduits is also underway along with continuing work on the 34.5 KV power feed bus.
Foundations for the right of way barrier walls are being installed between Herndon and Innovation Center, rebar for the barrier walls are visible on some of the foundations. Barrier wall installation continues to move east from Rudder Road to Horsepen Run.
Some preliminary ground work is taking place at Reston Town Center station.
Excavation at the Herndon station continues, a tower crane has also been erected on the track N2 side of the station.
The barrier walls along the entire length of the Innovation Center station are done. Columns that will support the mezzanine and mezzanine canopy are up to the level of the mezzanine.
The south straddle bent that will carry the elevated over the eastbound Access Road north of Aviation Drive was recently poured as it still has its protective blanket covering it. All of the columns west of the east elevated abutment in the median of the Access Road are near completion. The foundations for the straddle bent columns that will carry the elevated over the eastbound Access Road south of Aviation Drive have are done. One of the columns for the straddle bents that will carry the elevated over the eastbound Access Road south Aviation Drive has come out of the ground. No other column foundations work east of the airport station is underway.
Excavation of the airport station mezzanine is complete. The invert has been poured and preparation for the floor slab has begun. The Garage 1 pedestrian tunnel was closed on 01 11 2016 to allow the modification to the tunnel to allow the connection of the station entrance. See Section at Center Line Pedestrian Tunnel N10-NGA-A-303 in the airport station post for the detail of the modification.
All of the columns west of the airport station south of Aviation Drive are various stages of completion.
The remainder of girders have been set on the columns along Autopilot Drive to the 2nd column north of Materials Road. Pouring of the concrete deck has follow the setting of the girders. The contractor moved the cranes 9 columns north of Materials Road and began moving south, they have set 3 of those spans.
The yard lead columns appear to be mostly complete. Jersey barriers have been placed along the right shoulder of the westbound Dulles Greenway in preparation for the lane shift to allow the construction of the mainline elevated flyover, west yard lead elevated flyover, abutments and yard lead junction. No work in the Median of the Dulles Greenway has begun in this area.
Clearing and leveling that involves the use of explosives is taking place on the south side of the Dulles Greenway at the Loudoun Gateway station. (in my previous post I noted this as a staging area) Material from that clearing is being moved to entrance area north of the Dulles Greenway. No work in the median at the site of the Loudoun Gateway station has begun.
The east and west abutments at Broad Run have not been constructed.
A column in the median of Dulles Greenway that will carry Central Station Drive at the Ashburn station has been built. No work in the median at the site of the Ashburn station has begun.
Clearing of the site of the Dulles Yard is well underway. The contractor has graded what appears to be loop tracks at the south end of the site.

WMATA: Dulles Corridor Metrorail Project progress update e-mail 02 19 2016
DC to Dulles and Beyond: Metrorail on Track
Future track supports travel through the snow-covered woodlands at Dulles
Photo by Jennifer Alcott, Capital Rail Constructors.
The blizzard of 2016 and February's ice, rain and snow slowed construction of the second Phase of the Silver Line, but not very much.
While the blizzard piled up to 29 inches at Dulles Airport and 25 to 30 inches at points along the alignment, simply getting to the work site was the main problem for workers, project officials said.
Once onsite, workers spent many hours clearing the snow from construction sites, including the median of the Dulles International Airport Access Highway corridor, around cargo areas at Dulles Airport and near car rental agencies.
The snows turned the airport into a winter wonderland.
This photo, above, shows the girders that will support the future guideway for aerial tracks for the Silver Line west of the terminal and bound for the Ashburn area where the terminus station is being built. Actually not, those are the columns for the yard lead elevated that connects the mainline to Dulles Yard.
Construction of Phase 2 of the Silver Line from Reston to Ashburn has hit the 30 percent mark.
"We have continued to build momentum through good weather prior to the recent snow storm, and work is continuing," said Kevin Volbrecht, Project Director for Phase 2, Package A. "The storm didn't impact the critical underground hand-mining for future utilities in the Dulles airport highway corridor." Hand mining is required because of vast amounts of below-grade granite in the corridor.
At Dulles Airport, workers have recovered and removed the snow and are setting 84 and 72 inch girders, should read 84 and 72 foot girders, according to Volbrecht. However, the pouring of the giant concrete slab for the future Dulles Airport Metrorail Station was delayed to allow the snow to melt and drain.
During the first week of February, crews erected a large tower crane at the site of the future station to be located between Daily Garage One and Saarinen Circle and began pile driving necessary to support construction of the future Reston Parkway station. The project launched extensive public outreach to notify those who live, play and work in the Reston Town Center and other areas where the pile driving noise may be heard.
Noise from blasting to remove granite at the site of the future rail yard being built along Route 606 west of the terminal can be heard near Mercure Business Park. Alerts continue to warn drivers of temporary road closings caused by blasting.
Meanwhile, construction continues in the median of the Dulles International Airport Access Highway, at the future Herndon, Innovation, Dulles Airport and Loudoun Gateway stations. Project officials continue to be optimistic about the pace of construction. "We are expecting to make tremendous progress in 2016," Volbrecht said.

Pedestrian Bridge Closes to Make Way for the Silver Line
It should read pedestrian tunnel

The pedestrian tunnel between the main terminal and Garage 1 at Washington Dulles International Airport has been closed to permit construction of the future Dulles Airport Metrorail Station along the Silver Line.
The tunnel will remain closed for approximately two years, during which shuttle buses will carry travelers between the terminal and the garage. Shuttles will run every five minutes during peak travel hours to minimize delays.
"Maintaining pedestrian access is a primary concern as we undertake these changes," said Charles Stark, the Rail Project's Executive Director.
Extensive signage is in place throughout the airport to direct travelers. The Jan. 4 closing required extensive coordination with airport staff. Rail officials and airport staff will continue to monitor travelers' experience and make changes to signage, if needed.
Walkway access between Garage 2 and the main terminal remains open. The construction work includes multiple utility and communication line installations and reconfigurations. In addition, moving walkways must be shortened and adjusted to accommodate the new rail station at the mezzanine level of the airport.
When Metrorail opens, the tunnel will connect the station, as well as the garage, to the terminal.
Silver Line Support Straddle Bents Will Total 8
Gee, I wonder where they picked the term "Straddle Bent"
Photo, Capital Rail Constructors.
Crews working on the Dulles Corridor Metrorail Project successfully completed a significant operation on Jan. 8, by pouring 473 cubic yards of concrete needed to construct a large "straddle bent" over the Dulles International Airport Access Highway.
A straddle bent supports a structure that spans a particularly wide area where piers cannot be used directly beneath the span.
Massive concrete operations require significant coordination between project crews and the airport.
The work on Jan. 8 required 49 truckloads of concrete, and caused minimal interruptions to eastbound traffic along the Access Highway. The concrete pour took about 6.5 hours to complete, including preparation time.
To ensure structural integrity, several tests are conducted prior to pouring the concrete. Test cylinders are poured and post-tensioning cables are tested to confirm compliance.
As the project continues, it will require seven additional large straddle bents on or near airport property, including two more over the eastbound Access Highway lanes and one over the westbound lanes. This work is scheduled to be completed by the third quarter of 2016. Work on the four remaining straddle bents over the eastbound lanes of the Dulles Greenway is projected to begin in late 2016.

Dulles Corridor Metrorail Project Pictures 03 27 2016
Construction on all of the stations along the Dulles Access Road is now taking place. Excavation and pile driving for the foundation at the Reston Town Center station is well underway. The trees and brush have been cleared from the site for the Sunset Hills Road entrance on the north side of the station.
The Herndon Station has begun to come up out of the ground. The foundations are mostly complete over the entire length of the station. Forms for the first section of wall on the inbound side is in place. The wells for the hydraulic pistons of the mezzanine to platform elevators are in place.
The Innovation Center station continues to lead the race to completion. All of the columns up to the the mezzanine level are in place. The west ancillary has been topped out and has had its precast panels installed on both sides and the east end, the west end is sill open. Land on the south side of Sunrise Valley Drive has been cleared for the station entrance and parking garage.
Construction of the right of way barrier walls are at various stages of completion between Herndon and the east elevated abutment west of Rudder Road.
Ground work continues for storm drainage in the areas where right of way barrier walls has not commenced construction.
Mining for the utilities and traction power tunnels under the roadways of the access and toll road continues at various locations. The 34.5 KV power feed bus along most of the length of the Dulles Access Road is being trenched under the eastbound shoulder of the Access Road. Portions of the shoulder along Rudder Road north of the Dulles Assess Road have been milled off to allow the trenching of 34.5 KV power feed bus between the Access Road and Autopilot Drive.
The west straddle bent that will carry the elevated over the eastbound Dulles Access Road north of Aviation Drive is done. The forms have been set for the east straddle bent. I doesn’t look like concrete has been poured yet. South of Aviation Drive the columns for the two straddle bents, one over the eastbound and westbound Access Road, are done. None of the columns have come up out of the ground between Aviation Drive and the straddle bents south of Aviation Drive. Only one column between straddle bents south of Aviation Drive and the east end of Dulles Airport station have come up out of the ground.
At the Dulles Airport station, forms have been placed for the floor above of the mechanical room adjacent to the mezzanine to platform elevator pits. The first section of floor slab at the mezzanine level on the west end has been poured. Rebar for the second section is being placed. Rebar for the walls at the west end are also being placed. All of the columns for the station outside of the footprint of the mezzanine are at various stages of completion. The pedestrian tunnel has not been daylighted yet to make the connection to the station entrance. I think we can safely assume that is being held off to accommodate the shortening of the moving side walks and the modification of the profile in the part of the tunnel south of the station entrance.
Again all columns west of the Dulles Airport station are at various stages of completion including the columns along Airfright Lane south of the columns where the first girders were set.
The the decks on girders along Autopilot Drive between Rudder Road and Materials Road are done. Forms for the deck on the girders north of Materials Road extend out to just short of the east yard lead junction. Girders have been set to the last mainline column before the flyover and have been set roughly halfway between the east yard lead junction and the west yard lead junction.
Work on blasting to grade the site for Dulles Yard continues. It looks like the area for the shop building is being prepared for ground work.
Construction on the abutments for the Broad Run bridge have still not been completed.
No construction has begun at the sites of the station west of Dulles Airport. However jersey barriers are being placed at various location along both shoulders of the Dulles Greenway west of Old Ox Road VA-606.
I have now learned that the work being done west of the Old Ox Road VA-606 Dulles Greenway interchange is a VDOT project that will rebuild and upgrade the road to four lanes divided from west of the Dulles Greenway to west of the Loudoun County Parkway. At Horsepin Run, a bridge is being built next the to the exiting road at a higher elevation to eliminate the pipe culvert that drains Horsepin Lake into Broad Run.

WMATA: Dulles Corridor Metrorail Project progress update e-mail 04 13 2016
Major Work at Dulles Airport and All Stations Intensifying
The pace of construction of Phase 2 of the Silver Line, which will eventually connect Loudoun County, Dulles Airport, Reston and Herndon with downtown D.C. and the rest of the existing Metrorail System, is headed into a bustling construction period, according to Charles Stark, the Metropolitan Washington Airports Authority's executive director of the Dulles Corridor Metrorail Project (a.k.a the Silver Line).
"This is the biggest year so far for construction all along the Phase 2 alignment from Reston west to Ashburn," said Stark.The coming construction season is critical, he said. "There is a lot of work to be done."
A specific date has not been set for opening and it will be determined by the Washington Metropolitan Area Transit Authority after the Airports Authority finishes the line and transfers it to the regional agency.
Capital Rail Constructors (CRC), a joint venture of Clark Construction and Kiewit Infrastructure South, is the design-build contractor for all civil work, station and support facilities construction, bridges and aerial guideway structures, and train track and systems portions of Phase 2.
In recent months, CRC crews have made progress on the construction of the aerial guideway that will carry the Silver Line above Dulles Airport. Rail project officials have collaborated with airport executives and operations staff, airport users, employees and tenants such as cargo carriers and rental car agencies, to ensure construction does not interrupt critical traffic movements day or night.
The installation of 72" and 84" girders for the superstructure portion of the aerial guideway has progressed through the heavily treed areas of the northeast end of Dulles Airport toward the Dulles Greenway. Deck work to prepare the guideway for future track installation is taking place.
Two large straddle bents - each requiring between 380 and 489 cubic yards of concrete - have been constructed over particularly wide areas where piers cannot be used to support the spans. These aerial guideway elements are comprised of two vertical columns connected by a cap, also known as a "bent," and will support the girders and deck over the road crossings as trains enter and leave the airport. A total of four large straddle bents will be needed at Dulles, and an additional four will be built over the eastbound Dulles Greenway at night.
Concrete is placed on the deck of the Silver Line's aerial guideway at Dulles International Airport to prepare the deck for track installation.

Span 105 of the aerial guideway in the yard leads at the north end of Dulles International Airport marks the juncture where the Silver Line splits with the main line heading out to the median of the Dulles Greenway, and the secondary line heading to the rail yard.

All six stations-Reston Town Center, Herndon, Innovation Center, Dulles Airport, Loudoun Gateway and Ashburn-are currently in some stage of construction. In fact, Metrorail's distinctive exterior facade is already being installed at the Innovation Center Station. "You can easily tell that it is a station," project officials report.
This station, near the Center for Innovative Technology and Route 28, is a buzz of construction. Not only are station and access points coming along, Fairfax County is beginning work on the parking garage, and a private contractor is building a mixed-use complex nearby.
Here's what's happening at some of the other stations:
Low profile caps will support the girders and deck of the Silver Line where it will cross Autopilot Drive at Dulles International Airport.

The Dulles Airport Station site is a hive of activity as DCMP crews backfill the elevator machine room perimeter walls perform waterproofing and install steel rebar in preparation for the mezzanine mat pour.

Bus ramps, turn lanes work coming in Tysons
As a part of close-out of Phase 1, Dulles Rail project contractors will soon be making some repairs for the bus ramps and turn lanes at the McLean and Spring Hill Metrorail Stations. Dates and times will be released in advance of the work.
Working together near future Herndon Station
Rail project and Fairfax County officials are working together to coordinate duct bank and other work near the future Herndon Rail Station. The rail team (Capital Rail Constructors) is building the rail line and station and the county is building the parking garage. Coordinating schedules is maximizing efficiencies as both teams work almost side by side.

Major Work at Dulles Airport and All Stations Intensifying
The pace of construction of Phase 2 of the Silver Line, which will eventually connect Loudoun County, Dulles Airport, Reston and Herndon with downtown D.C. and the rest of the existing Metrorail System, is headed into a bustling construction period, according to Charles Stark, the Metropolitan Washington Airports Authority's executive director of the Dulles Corridor Metrorail Project (a.k.a the Silver Line).
"This is the biggest year so far for construction all along the Phase 2 alignment from Reston west to Ashburn," said Stark.The coming construction season is critical, he said. "There is a lot of work to be done."
A specific date has not been set for opening and it will be determined by the Washington Metropolitan Area Transit Authority after the Airports Authority finishes the line and transfers it to the regional agency.
Capital Rail Constructors (CRC), a joint venture of Clark Construction and Kiewit Infrastructure South, is the design-build contractor for all civil work, station and support facilities construction, bridges and aerial guideway structures, and train track and systems portions of Phase 2.
In recent months, CRC crews have made progress on the construction of the aerial guideway that will carry the Silver Line above Dulles Airport. Rail project officials have collaborated with airport executives and operations staff, airport users, employees and tenants such as cargo carriers and rental car agencies, to ensure construction does not interrupt critical traffic movements day or night.
The installation of 72" and 84" girders for the superstructure portion of the aerial guideway has progressed through the heavily treed areas of the northeast end of Dulles Airport toward the Dulles Greenway. Deck work to prepare the guideway for future track installation is taking place.
Two large straddle bents - each requiring between 380 and 489 cubic yards of concrete - have been constructed over particularly wide areas where piers cannot be used to support the spans. These aerial guideway elements are comprised of two vertical columns connected by a cap, also known as a "bent," and will support the girders and deck over the road crossings as trains enter and leave the airport. A total of four large straddle bents will be needed at Dulles, and an additional four will be built over the eastbound Dulles Greenway at night.
Concrete is placed on the deck of the Silver Line's aerial guideway at Dulles International Airport to prepare the deck for track installation.

Span 105 of the aerial guideway in the yard leads at the north end of Dulles International Airport marks the juncture where the Silver Line splits with the main line heading out to the median of the Dulles Greenway, and the secondary line heading to the rail yard.

All six stations-Reston Town Center, Herndon, Innovation Center, Dulles Airport, Loudoun Gateway and Ashburn-are currently in some stage of construction. In fact, Metrorail's distinctive exterior facade is already being installed at the Innovation Center Station. "You can easily tell that it is a station," project officials report.
This station, near the Center for Innovative Technology and Route 28, is a buzz of construction. Not only are station and access points coming along, Fairfax County is beginning work on the parking garage, and a private contractor is building a mixed-use complex nearby.
Here's what's happening at some of the other stations:
- Reston Town Center: Pile driving and other preliminary station work will continue through April. This spring, the first tower crane at the Reston site will go up in the median of the Dulles International Airport Access Highway (DIAAH), to be followed shortly by a second tower crane at that location, and will bring the total number of tower cranes concurrently in use on the project to five.
- Herndon: A tower crane has been in place for months to facilitate station construction. Preliminary road changes and bus re-routings at the Herndon-Monroe Park & Ride facility have taken place as utility and other prep work speeds up, especially along Sunrise Valley Drive. Work on a traction power substation near Herndon Station is starting. This is one of several sites where the hardness of below-ground rock is forcing crews to do hand-mining rather than use drills to break through.
Low profile caps will support the girders and deck of the Silver Line where it will cross Autopilot Drive at Dulles International Airport.

The Dulles Airport Station site is a hive of activity as DCMP crews backfill the elevator machine room perimeter walls perform waterproofing and install steel rebar in preparation for the mezzanine mat pour.

Bus ramps, turn lanes work coming in Tysons
As a part of close-out of Phase 1, Dulles Rail project contractors will soon be making some repairs for the bus ramps and turn lanes at the McLean and Spring Hill Metrorail Stations. Dates and times will be released in advance of the work.

Loudoun Gateway Station Excavation Begins Tuesday, April 26
Construction Activities on the Dulles Greenway Continue to Build
Starting today, Tuesday, April 26, and continuing through the summer months, Dulles Corridor Metrorail Project crews began site clearing and excavation work for the Silver Line's future Loudoun Gateway Station in the median of the Dulles Greenway. The station will be located west of the Old Ox Road overpass.
The work at the Loudoun Gateway Station requires large, slow-moving vehicles and equipment to exit and enter the highway in the eastbound and westbound lanes at various times.
Please Drive Carefully!
Silver Line construction activity on the Dulles Greenway will continue to build. Following this site work, construction of the Loudoun Gateway Station will begin. Motorists will see an increase in the number of construction vehicles that will be sharing the road and lane and shoulder closures will occur at various locations and times. For your safety and the safety of construction workers, drivers are encouraged to slow down and drive carefully, giving full attention to the road and the possibility of changing conditions.

WMATA: Dulles Corridor Metrorail Project progress update e-mail 06 13 2016
Silver Line Phase 2 Construction Ramps Up
Steady progress continues on Phase 2 of the Dulles Corridor Metrorail Project with the design nearly complete and ample elements to capture curious eyes.

As construction continues to ramp up through 2016, commuters will see work along the entire 11.4 - mile stretch of Phase 2, which extends from the existing Wiehle-Reston East Station westward to Dulles International Airport and beyond to Ashburn in Loudoun County.
"This is the biggest year so far for construction all along the Phase 2 alignment from Reston west to Ashburn," said Charles Stark, the executive director for the project. "there is a lot of work to be done."
Currently, the project's design is 99.3 percent complete and construction is around 17 percent complete.
Considerable work has been done at Dulles Airport and at the Innovation Center Station site, which is the first station to the east of the airport. Traversing the Dulles Airport property requires the use of an aerial guideway consisting of drilled shafts, columns, caps, girders, decks and other engineering elements. The shafts, columns and caps are mostly complete with about 200 girders set along the guideway.
In addition to the aerial guideway, considerable work has been done at the Dulles Airport Station site adjacent to Garage 1. The pedestrian tunnel running from Garage 1 to the main terminal has been closed to permit construction of the station. Once work has finished, the tunnel will reopen to provide access for those parking in the garage as well as those arriving or departing via Metro.
The future Innovation Center Station site has experienced the most progress, taking on the look of the Phase 1 Stations, while enabling and excavation work continues at most of the other five stations comprising Phase 2. Ashburn remains an exception but excavation work is expected to begin there later this year.
Crews continue to supplement their restricted daytime schedules with night work along the alignment.
The Journey Continues at Dulles Airport Station
Pictured below is the latest rendering of the highly anticipated Dulles Airport station. Dulles will be the only station to have different design aspects apart from the rest of the metrorail. The station intends to resemble the terminal's sleek and iconic design. Passengers will be able to access the terminal through a pre-existing tunnel originating at Parking Garage 1. The tunnel is closed during construction but when reopened it will provide ease of access with multiple moving walkways.

What's Happening at Horsepen Lake?
Pictured below, the Capital Rail Constructors girder crew sets a precast concrete girder over Horsepen Lake at Dulles International Airport. This aerial guideway will carry metrorail cars to and from the new rail yard and maintenance facility that is being constructed as part of Phase 2 of the Silver Line. At 150 feet long, the four girders that will span Horsepen Lake are the longest and heaviest girders in the aerial guideway.

On June 3, reporters from Loudoun Now toured the construction site of Innovation Center Station.
On June 4, employees from the Dulles Corridor Metrorail Project answered questions about Phase 2 and handed out goodies to the public at the 36th Annual Herndon Festival.
On May 23, members from the American Society of Civil Engineers took a closer look at Dulles Airport Station and the construction of the aerial guideway.

Progress report from last week's MWAA board meeting
If you're looking for reading material to pass the time between now and the projected opening of the Silver Line to IAD in 2020 (sigh...), the monthly meetings of MWAA's board of directors typically include a progress report. Here are some highlights from last week's gathering:
• Overall design is 99% complete and overall construction is 30.9% complete.
• Along the aerial segment going through IAD, 85% of the columns have caps in place, 33% of the concrete decks to go over them have been poured, and 3 of the 8 "straddle bent" beams spanning roadways have been installed.
• The IAD station should begin emerging from its foundations in September.
A separate PDF reports more details about current and projected expenses and throws in a separate batch of photos of construction along the Toll Road, the Greenway and at the future rail yard north of IAD.
