Bridges are our passion.  Being industry leaders drives our projects


SW 198th Ave. Improvement Project
Hillsboro, Oregon 

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.  

US101: New Youngs Bay Bridge Repair
