South Atlantic Street overpass open to traffic

Posted on Jan 27 2014 5:14 PM

On Monday, Jan. 27, we opened a new overpass to the west of Seattle’s stadiums. The overpass allows traffic to bypass a busy railroad track that crosses South Atlantic Street. Before the overpass, train activity often blocked traffic for extended periods, which not only slowed truckers traveling to and from the Port of Seattle, but also created backups that stretched onto Seattle streets and Interstate 90. The overpass saves truckers as much as 20 minutes of travel time between the port and I-5 or I-90. 

The section of Atlantic beneath SR 99 will remain closed to through traffic until the SR 99 tunnel opens to traffic. Drivers will now use the new overpass to travel in both directions between Atlantic and Alaskan Way South. 

Later this winter, crews will complete improvements to the bicycle and pedestrian path on the west side of SR 99 between Atlantic and South King streets. 

The north leg of the overpass will open to the public after the tunnel opens and will eventually link traffic to the new Alaskan Way and Seattle waterfront
