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.
Construction work on the bridge will begin in March, 2021. Expect to see delays and some single lane closures at night throughout the project. Flaggers will be on site when this occurs. Portable message boards will display construction impacts on both sides of the bridge to alert travelers.
Full weekend closures will take place from Labor Day 2021 through Memorial Day 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, the detour will route traffic across the bridge at Biggs Junction.
