Taking I-90 from Indiana should be no problem at that time of the day. all of the construction on I80-94 has been completed in Indiana. Parking is going to be very expensive near the station. The parking garage to the south next to the station had a special price if you were taking Amtrak, however the last time I used it, they no longer honored the special rate. Have a great trip on the Empire Builder it is one of my favorite routes.
