The Oregon Department of Transportation is instating a temporary 35 mile per hour speed limit on The Dalles Bridge to aid the efforts of maintenance crews trying to make pothole repairs.  The temporary speed limit will remain in place as pothole work continues, likely until the latter part of March or early April, when weather conditions permit more permanent repairs to be completed.  Sign crews will also be installing “rough road” signs to alert motorists to the surface conditions on the bridge, until those more permanent pothole repairs are completed.
