Drivers can expect a complete closure of the Historic Columbia River Highway at the Chenoweth Creek Bridge west of The Dalles city limits for the next three weeks.  The Oregon Department of Transportation says the bridge will be closed for a three week period while crews from Wildish Standard Paving replace the failing bridge.  The bridge is expected to re-open on August 25.  This work is being done in conjunction with additional repairs to the Mosier Creek and Dry Canyon Creek bridges on the Historic Columbia River Highway between Mosier and The Dalles.  During the closure, motorized traffic will be detoured via Exit 76, Rowena.  Bicyclists and pedestrians should follow signed detour routes to The Dalles Waterfront Path.
