WSDOT Traffic Advisory
On Monday, April 25, crews will close the remaining southbound lane on Alaskan Way S. between S. Atlantic Street and S. Royal Brougham Way to relocate railroad tracks and create room for the new SR 99 roadway. The closure will begin at 5 a.m., April 25 and remain in place 24 hours a day, seven days a week for the next three years.
Access to the Port of Seattle’s Terminal 46 via Alaskan Way S. will be maintained for freight haulers; drivers will follow a signed detour onto East Frontage Road S., the new street east of the viaduct between S. Atlantic Street and S. Royal Brougham Way. Bicycles and pedestrians will be detoured around the closure using the Alaskan Way S. multi-use trail.
This work is part of the S. Holgate Street to S. King Street Viaduct Replacement Project. WSDOT is replacing the southern mile of the Alaskan Way Viaduct with a new side-by-side roadway that meets current earthquake standards, has wider lanes and improves mobility and goods in the south of downtown area.
