This project will rehabilitate the deteriorating concrete bridge deck for the Mullan Road Bridge over I-90. Crews will remove approximately 1.5 inches of existing concrete through hydro-demolition. Once removed, existing reinforcing steel that is exposed will be evaluated to determine the need and extent of repair. Once complete, a new 2-inch modified concrete surface will be constructed to preserve the bridge deck for years to come.
The bridge was constructed in 1975 and is the original concrete bridge deck. This work is necessary to rehabilitate the deteriorating bridge deck. There has been no major rehabilitation to the bridge deck except for the patching that is currently visible. Crews will be removing approximately 1.5 inches of the existing concrete deck surface and existing patchwork using hydro-demolition. Once complete, travelers will be driving on a new 2-inch modified concrete surface which will preserve the integrity of the bridge deck for years to come.
The project is scheduled to last 51 working days. Contractor crews will begin work in the spring of 2022.
