WSDOT‘s newest Highway 99 tunnel update is out, and the state says that Seattle Tunnel Partners‘ newest schedule indicates “the tunnel could open to drivers as soon as this fall.” They’re not ready to estimate a date yet, and WSDOT notes that a “significant amount of work remains between now and tunnel opening,” but it’s getting closer. And WSDOT’s update includes the reminder that when “the tunnel is ready to open, SR 99 through downtown Seattle will be closed to traffic for approximately three weeks” so that connections can be finalized. You can read the entire update here.
P.S. As we’ve been reminding you in the morning traffic/transportation updates, the Battery Street Tunnel will be closed for four hours this Saturday morning, 6-10 am, for an inspection related to its future decommissioning
