Exposed expansion joint
An exposed bridge expansion joint on the westbound I-90 East Channel Bridge near Mercer Island.
Crews chipped out concrete a foot thick and three feet on either side of the expansion joint to free it from bridge deck.
The expansion joint is one of two on the bridge that is being replaced in this critical highway safety and preservation project.
The expansion joints on the westbound East Channel Bridge are 33 years old. The steel has cracked and the rubber seal is broken. Replacing the joints helps preserve the integrity of the bridge and keeps drivers safe.
