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.

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. ​
