About the Project

Multnomah County has led the effort to replace this 90-year old Willamette River crossing with a new, seismically-sound structure that offers upgraded facilities for all users. Traffic on the new bridge is open. Major work on the bridge is complete. Clean up work and construction on the ground will continue into early 2017.

This project is an ongoing effort by Multnomah County to replace this 90-year old Willamette River crossing with a new, seismically-sound structure that offers upgraded facilities for all users. Traffic on the new bridge is now open, though drivers should allow extra time to cross the bridge on weekdays due to construction.

T.Y. Lin International Wins 2017 ACEC Honor Award for Sellwood Bridge Replacement

Maribel Castillo Executive Director, T.Y. Lin International - April 26, 2017

T.Y. Lin International (TYLI), a globally recognized, full-service infrastructure consulting firm, announces that the Sellwood Bridge Replacement project (Sellwood Bridge) in Portland, Oregon, has received an Honor Award in the 2017 Engineering Excellence Awards competition of the American Council of Engineering Companies (ACEC). TYLI served as Prime Consultant, Final Design, on the fast-track project, working closely with the Project Owner, Multnomah County, design subconsultant CH2M, and Construction Manager/General Contractor, Slayden/Sundt Joint Venture. The 2017 Honor Award was presented to the TYLI team at the ACEC Engineering Excellence Awards Gala on April 25, 2017, in Washington, D.C.

The Sellwood Bridge across the Willamette River opened to traffic on February 29, 2016, and replaces a deteriorating fixed span structure built in 1925. The 1,976-foot-long bridge, 1,275 feet of which is a steel deck arch, features three arch spans that support the 63- to 90-foot-wide deck of the main river spans. The new, seismically resilient bridge carries two 12-foot-wide vehicular lanes, two 6.5-foot-wide bike lanes/emergency shoulders, and two 12-foot-wide shared-use sidewalks. TYLI also designed the bridge to accommodate future streetcar service.

Sellwood Bridge Field Work Notice - February 17, 2017

Hazard markers for old bridge pier that will be removed in summer 2017

Hazard markers for old bridge pier that will be removed in summer 2017

Field Work Notice - February 17, 2017

The Sellwood Bridge contractor is working on punch list tasks as construction wraps up.

Question of the Week: Why the hazard markers in the river? Several people have asked us recently about two hazard markers rising from an object in the river near the bridge.  The poles mark the location of a concrete river pier from the old Sellwood Bridge.  This pier could not be removed during construction of the new bridge so it will be removed during the in-water work period this summer.

TRAFFIC

Hwy 43: There will be brief traffic delays on Tuesday, Feb. 21 during non-peak hours in the through lanes under the bridge as workers in a manlift adjust overhead signs.
