The bridge is the most significant project feature. It connects the carriage pavilion, a covered drop-off area on the west side of the station, with the third level of the parking garage. Serving both pedestrians and vehicles, it allows visitors — for the first time ever — to approach the front of Union Station and drive directly to the garage instead of circling to the back of the building. Construction teams installed 66,000 pounds of rebar to support the nearly 180 cubic yards of concrete — nearly 20 truckloads of cement. Teams designed and built bridge piers, precast garage spandrel infill, a bridge deck, drainage and piping, electrical and more, all while business carried on as usual inside the station.
