In September 2020, the northbound bridge of the Interstate Bridge will close for up to two weeks as crews replace a cracked trunnion and other parts that help lift and lower the bridge. During the closure, all traffic crossing the bridge will share the southbound bridge and sidewalks. The Interstate Bridge is located on Interstate 5 where it crosses the Columbia River between Portland, Oregon and Vancouver, Washington.
This important maintenance work is necessary to keep the bridge in working order. Because this work takes place overhead, the northbound bridge must close to keep drivers safe and to provide access for construction crews and heavy equipment. We are preparing extensively for this project to ensure the shortest possible closure period.
