A contractor will be crack sealing some streets in The Dalles beginning today and continuing throughout the week.  Portions of Brewery Grade, West 10^th, East 10^th, East 12^th, and Thompson Street will be the locations of the work.  Work will begin at 7 a.m. each day, and no parking signs will be placed at those locations at least 48 hours before the location is scheduled for sealing.  The crack seal projects will require short-duration single-lane closures for the protection of workers and to allow time for the seal to set.  Motorists are asked to watch for crews and avoid driving on the rubberized asphalt crack seal until it is set.
