The State Route 433 Lewis and Clark Bridge connecting Longview, Washington and Rainier, Oregon will close to vehicle traffic for up to eight days beginning 8 p.m. Sunday, July 16 as we replace two bridge expansion joints and a fractured floor beam.

During the full bridge closure, all traffic crossing the Columbia River will detour to either the Astoria-Megler Bridge between Megler, WA and Astoria, OR, or the Interstate 5 Bridge between Vancouver, WA and Portland, OR.

Project construction is estimated to begin the week of June 12 and travelers should expect traffic delays or detours for approximately five weeks. Before and after the full closure, the bridge will be a single lane of alternating traffic starting at 8pm each night. Travelers should expect longer delays and congestion in the area.

We know this has a significant impact on the community and want to get this work done as quickly and efficiently as possible. To stay informed about the project as it progresses, you can subscribe to email updates here
