Broadway Bridge Rehabilitation

Under a Local Agency Federal Aid contract with the Oregon Department of Transportation, DEA provided full preliminary engineering and construcion engineering assistance for the rehabilitation of the 90-year-old Broadway Bridge in Portland, Ore.

Bridge improvements included replacing the steel open-grid deck with a new fiber-reinforced polymer deck system; replacing the existing paint system; repairing structural defects; installing a new storm water collection, distribution, and treatment system; and balancing the bascule spans pre- and post-construction.

Additionally, DEA provided a partnering facilitator for the engineering and construction phases, public involvement program support, permitting services, and developed a biological assessment, historic resource compliance documentation, and a bidder pre-qualification program.
