The Dalles Public Works on Monday will begin a sanitary sewer main construction project on East 9^th St. between H Street and I Street to provide service to new homes being built in that area.  Construction will take about two weeks.  Full road closures will be in effect during work hours from 7 a.m. to 3 p.m. weekdays.  No parking within the work area will be allowed during work hours due to heavy equipment use and the location of the trench.  Detours will be in place during work hours on H Street and East 8^th Street, east and west alley access on H Street between East 8^th St. and East 9^th St., H Street and East 9^th Street, and I Street and East 9^th Street.
