Crack sealing of streets in The Dalles will begin on Wednesday in the downtown core area and progress to other areas throughout town over the summer months.  The purpose of crack sealing is to extend the useful life of asphalt streets by preventing water intrusion into cracks.  Work will be done in one-block sections, closing one lane at a time to allow traffic to continue to flow.  The partial closures will be in place for one hour or less depending on the severity of the cracking.  For questions or concerns, please contact The Dalles Public Works office at (541) 296-5401, extension 2001.
