Digging it out
One of the expansion joints on the westbound I-90 East Channel Bridge near Mercer Island, WA is slowly exposed by contracgtor crews. The expansion joint is embedded in concrete nearly a foot deep. Exposing it is hard, time-consuming work.
Contractor crews are replacing the two expansion joints on the bridge because they've outlived their useful lifespan. The joints are 33 years old and deteriorating. There are cracks in the steel and the rubber seal is broken.
Replacing the expansion joints is necessary to preserve the bridge and ensure the safety of drivers.
