This innovative track bridge will be installed at the location of expansion joints (some are at right of man taking photo) on the I-90 bridge to enable light rail vehicles to cross the floating bridge. Cars can accommodate the moving bridge when they drive over the expansion joints — tracks can not because they can not move out of alignment. The track bridge will allow for movement without changing alignment of the tracks.

Eight track bridges will accommodate lake motion, and the specialized track attachments will allow trains to operate on the floating bridge when the Blue Line opens in 2023, according to a Sound Transit press release. Shot Tuesday, July 23, 2019.
