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

Construction Phase

Region 4: Central Oregon (The Dalles, Wasco)


​​​​​​​​​​​​​​​Bridge Safety Project

Impacts

Construction Impacts

Since last summer crews have been working on replacing the bridge deck on U.S. 197 over the Columbia River, but unexpected delays have extended the project timeline. 

As of September 29, weekend closures have resumed on The Dalles Bridge. Closures are Thursday nights from 8 p.m. through Monday mornings at 6 a.m., and will continue into spring of 2023. Unexpected delays like severe winter storms could extend this timeline. The bridge will be open for the weekends of Thanksgiving, Christmas, and New Years. 

When the bridge is closed, a detour will be in place through Biggs Junction (see map below). You can always check TripCheck.com for up to date information on construction, closures, and detours. 

Without these closures, there is no other way for crews to complete the complex deck replacement. These continued closures ensure that the bridge won't be entirely shut down for an extended period of time. 

Emergency responders like police, fire and EMS will be able to use the road on the dam for emergency access across the river. ​

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. ​
