U.S. 197: The Dalles (Columbia River) Bridge Deck Replacement

Construction Phase

Region 4: Central Oregon (The Dalles, Wasco)


​​Bridge Safety Project

Impacts

Traffic Impact

During construction when The Dalles Columbia River Bridge is closed, traffic will be re-routed to the east using I-84 to Biggs Junction, across the Columbia River into Washington and using U.S. 97 to S.R. 14 west to U.S. 197. 

Construction Impacts

Construction work on the bridge will begin in March, 2021. Expect to see delays and some single lane closures at night throughout the project. Flaggers will be on site when this occurs. Portable message boards will display construction impacts on both sides of the bridge to alert travelers.

Full weekend closures will take place from Labor Day 2021 through Memorial Day 2022. During these weekends, the bridge will close Thursday nights at 8 p.m. and will re-open on Monday mornings at 6 a.m. During these closures, the detour will route traffic across the bridge at Biggs Junction. See map.

What Problem Will This Improve?

This steel-truss-cantilever bridge on U.S. 197 was constructed in 1953. The existing bridge deck is failing and needs to be replaced. This bridge crosses the Columbia River and is a crucial connection point between the Dalles, Oregon and Dallesport and Murdock, Washington. This project will remove and replace the exisitng bridge deck and make critical safety repairs. ​
