Construction Impacts

Construction work has already begun. Currently, travelers can expect to see delays of up to 20 minutes weeknights between 8 p.m. and 6 a.m. due to single lane closures. During these times, traffic will be controlled by flaggers. A temporary construction speed zone has been put in place across the bridge, reducing the speed to 35 mph.  This speed reduction will remain in effect until the project is completed next year.

Full weekend closures of The Dalles Bridge have begun, and will and last until the weekend before Memorial Day 2022. Closures are scheduled from 8 p.m. Thursday nights through 6 a.m. Monday mornings. 

During these closures, a 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.
