The new SR 99 tunnel under downtown Seattle
The #realign99 highway closure set to begin Jan. 11, 2019. Make your plan!
Getting around using the tunnel
The new tunnel will provide a direct route under downtown from the stadiums to the Space Needle. The south end connects to Alaskan Way and downtown, the north end connects to Seattle Center and South Lake Union.
Viaduct removal starts early 2019
The Alaskan Way Viaduct will remain open until the #realign99 closure begins. Shortly after the tunnel opens, crews will begin removing the viaduct, as well as closing and filling the Battery Street Tunnel and rebuilding three blocks of Aurora Avenue North.
