SR 99 - S Holgate Street to S King Street Viaduct Replacement - Reducing number of travel lanes

Two out of three lanes open on Alaskan Way Viaduct south of the stadiums

As of Sunday, May 15, both directions of a section of the SR 99 Alaskan Way Viaduct corridor have been reduced from three to two lanes between the West Seattle Bridge and Seattle's sports stadiums. The lane reduction provides crews the space they need to continue construction of the new southbound lanes. What can drivers do?

The southern mile of the viaduct corridor will remain two lanes in each direction through 2013 and possibly longer, until the central waterfront section of the viaduct is replaced.

We've reduced the speed limit to 35 mph on the southern mile of the Alaskan Way Viaduct corridor. Please drive safely and watch for roadside work crews and equipment in the active construction work area. The active work area is located along the west side of the viaduct, just south of Safeco Field where the SR 99 viaduct becomes a double-deck roadway.

Getting around during construction   

  • Know before you go: Drivers may want to use alternate routes such as I-5 and surface streets to get to the ballpark. Real-time conditions on the Alaskan Way Viaduct and many connecting streets can be found on the city of Seattle's Traveler's Information Map. Real-time conditions on Seattle area freeways can be found on our Seattle Area Traffic Map.
  • Know where you will park: Most of the on-street parking spaces underneath the viaduct between S. King Street and S. Atlantic Street have been removed. However, there are several parking options in the area including garages and pay lots.
  • Take Link Light Rail or the bus: Sound Transit Link Light Rail stops right near Safeco Field, and there also are several Metro bus routes that stop within a few blocks of the stadium.
