The Dalles Public Works Department will begin a street reconstruction project Wednesday on West 6th Street from Mt. Hood Street to Trevitt Street.  The east and westbound travel lanes on West 6th will be closed to all traffic between 7 a.m. and 5 p.m.  Motorists, bicyclist and pedestrians are asked to use alternate routes around the work zone during the closures.  The purpose of this project is to smooth the eastbound approach to the 6th Street Bridge.  Motorists are asked to proceed with caution around work areas during construction times and observe all temporary traffic control devices.
