Travelers should plan ahead for closures on SR 99/Aurora Avenue North between the south end of the Battery Street Tunnel and Valley Street, May 8-10. The Alaskan Way Viaduct will remain open during this time.
During the closures, crews will connect a new water main under the highway near Harrison Street – a critical step toward building the on- and off-ramp connections for the SR 99 tunnel’s future north portal. Seattle City Light crews will also take advantage of the closure to remove overhead power lines.
WSDOT is timing the closures to help Mariners fans get to and from the games that weekend.
