Construction Impacts

Currently, one traffic lane may be closed on the bridge nightly, from 8 p.m. until 6 a.m. the following morning.  During these times, traffic will be controlled by flaggers with up to 20 minute delays to the traveling public any night of the week, from now throughout the life of the project, which is planned to end in June 2022. Travelers should plan accordingly for these possible delays. There will be no full bridge closures until after Labor Day 2021. 

Full weekend closures will take place from Labor Day (September) 2021 through Memorial Day (May) 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, 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.
