The Dalles Bridge will close at 8 p.m. this evening and be shutdown until 6 a.m. Monday in the first of a series of closures that will occur every weekend through Memorial Day of next year as the Oregon Department of Transportation does a bridge deck replacement project.  ODOT’s Peter Murphy says doing the re-decking in winter is not ideal, but it does avoid impacting tourist and harvest seasons.  ODOT has worked with the Army Corps of Engineeers to allow emergency vehicles to cross the Columbia River at The Dalles Dam when necessary.
