- Installing bridge screening over the locks and BNSF Railway
The Dalles Columbia Bridge spans the Columbia River between The Dalles, OR and Dallesport, WA.
Cost and Funding
Total project cost is just under $41 million. The cost is shared 50/50 with Washington Department of Transportation.
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 existing bridge deck and make critical safety repairs.
