The Dalles Public Works will begin work Monday to replace the sanitary sewer line and install a new storm line in Trevitt Street between 7th Street and 9th Street.   Work will take place weekdays from 7 a.m. to 3 p.m. through April 1.  For the duration of the project Trevitt Street will be closed from 7th to 9th Streets to all traffic, including emergency vehicles, with no parking allowed along either side of Trevitt Street in the immediate work area.  Motorists are encouraged to use Bridge and Garrison Streets as alternative routes to avoid the work area.  8th Street residents will need to use Bridge Street for access to their homes, as 8th Street will be closed at the intersection with Trevitt Street.  If you have questions or concerns, call The Dalles Public Works office at (541) 296-5401, extension 2001.
