In June, we reported on WSDOT’s plan to close part of Highway 99 (including the Alaskan Way Viaduct) in late August for repair work. Today, new details are out – see them here – since WSDOT has locked in more details. Key points: 99 will be closed both ways from the West Seattle Bridge to Valley Street from late Friday night, August 22nd, until early Monday morning, August 25th; the section from the WS Bridge to the Battery Street Tunnel will reopen then, but the stretch north to Valley will remain closed until Wednesday, August 27th.
P.S. If you have questions about ongoing Highway 99 work, including (or not) the tunnel, WSDOT has a booth here at West Seattle Summer Fest, all weekend long.
