Traffic to be detoured through Williams Avenue South

WHAT: Both southbound lanes of Main Avenue South, from South 4th Street to City Hall, will be closed to traffic to allow for construction of 1500 feet of a water main in Main Avenue South and Benson Road South. The new 16-inch diameter water main will replace the last remaining portion of the existing aging pipe. In 2010, WSDOT 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 S.

WHEN: Construction will begin June 20, 2011, 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. Construction is expected to last through early September.

WHERE: Main Ave South and Benson Road South southbound, between South 4th Street and Renton City Hall, will be closed to traffic during construction, and will be detoured through Williams Avenue South.
