The Port of Seattle is constructing a bridge that will connect the South Satellite Terminal with the new International Arrivals Facility (IAF).
The prefabricated bridge was planned to be moved into position yesterday overnight. The construction firm is estimating 7 days to safely secure the bridge in place before aircraft will be allowed to taxi underneath. During this seven day period, taxi movement will be severely impacted. Reduced Airport Arrival Rates, increased gate holdouts, loss of gates and ATC Initiatives (TBFM, MIT & GDPs). The FAA and Port Authority are anticipating significant impact to the operations of those airlines in the South Complex, and to the airport due to reduced arrival rates.
So we'll have a cool new bridge over the AOA to walk on, ala Denver, but for the next week its going to cause some degree of slowdowns due to the reduced real-estate.
