Both southbound lanes of Main Avenue South from South Fourth Street to City Hall will be closed to traffic during the day for construction of 1,500 feet of a water main in Main Avenue South and Benson Road South.
Construction begins Monday, June 20, from 8:30 a.m. to 3:30 p.m., Mondays through Fridays. Both southbound lanes will be re-opened to traffic at 3:30 p.m. daily in time for the afternoon commute.
Construction is expected to last through early September.
The contractor will have a signed detour route that will use South Fourth Street and Williams Avenue South to Grady Way. Williams Avenue parallels Main Avenue.
The new 16-inch diameter water main will replace the last remaining portion of the existing aging pipe. In 2010, the Washington state Department of Transportation replaced a portion of the old water line as part of the I-405 Stage 2 widening project to accommodate the construction of the new freeway off-ramp and the realignment of Benson Road South.
