SEATTLE – The southbound State Route 99 off-ramp near Seattle’s stadiums will make a weekend move as contractor crews working for the Washington State Department of Transportation continue construction on the new South Atlantic Street overpass.

Currently, the ramp connects to East Frontage Road on the west side of SR 99, but starting Monday morning, April 1, the ramp will drop drivers off at a new intersection at South Atlantic Street (pdf 345kb) and Colorado Avenue South. From the intersection, drivers will be required to turn left onto South Atlantic Street to head east toward First Avenue South, the stadiums, and the on-ramps to Interstate 5 and I-90. Crews will close the ramp this weekend to complete the new connection to South Atlantic Street.

Closure details

  • Crews will close the southbound SR 99 off-ramp at 5 a.m. Saturday, March 30.
  • The ramp will reopen by 5 a.m. Monday, April 1, in its new configuration.

“Drivers should expect some extra congestion and delays as they adjust to the ramp’s new configuration,” said Matt Preedy, deputy administrator for the Alaskan Way Viaduct Replacement Program. “When the ramp reopens we’ll keep an eye on how traffic flows and will fine-tune signals to keep traffic moving on the ramp and on South Atlantic Street.

The South Atlantic Street overpass is part of the Alaskan Way Viaduct Replacement Program. Overpass construction started last summer and is scheduled for completion by the end of 2013. The overpass will improve mobility by allowing freight haulers, daily commuters, pedestrians and bicyclists to bypass the surface rail crossing in front of the entrance to the Port of Seattle’s Terminal 46.
