The Dalles Public Works Department will work on a pavement preservation project next week on West 6th Street west of Cherry Heights Road.  The eastbound lane on West 6th Street will be closed during work hours on Monday and Tuesday, while the westbound lane on West 6th Street will be closed next Wednesday and Thursday.  Work hours will be 7:00 a.m. to 5:00 p.m. each day.  Motorists, bicycles and pedestrians are asked to use detours around the work zone during work hours.  The street will be reopened to the traveling public each evening.  Walk up business access will be open during construction.  For safety reasons, parking on West 6th Street within the work zone will not be allowed until the project is complete.  The purpose of this project is to grind out the wheel ruts and replace approximately 500 feet of pavement in each lane.  Crews will also grind and replace pavement in a larger area that needs to be patched.
