SW 198th Ave. Improvement Project
Working with Washington County, under a general contractor, on SW 198th Ave from SW Farmington Road to SW Tualatin Valley Highway, OSBC is completing the structures on this project. Culverts were removed from two creeks and replaced with two 30 foot single span precast deck bridges over each creek. Critical to the schedule was the coordinated work between the General Contractor and all utility companies.

Work consists of bridge jacking and replacing bearings at each pier, installing a bridge cathodic protection system, and all damaged concrete surfaces underneath the bridge receives a new concrete surface and coating application. Work access is by barge only to the engineered scaffolding system underneath each bridge span.
