Southbound SR99 lanes will be closed for construction next two weekends
Safety pilings being installed for SODO overpass
WSDOT press release:
Drivers should plan for delays on southbound State Route 99 through downtown Seattle the next two weekends. Crews working for WSDOT will reduce SR 99 to one lane near the stadiums and close the southbound off-ramp to South Atlantic Street.
During the closures crews will drive more than 50 pilings to support construction of the new South Atlantic Street overpass.
“The pile-driving work will happen in a tight space just a few feet from the right lane of SR 99 and the off-ramp,” said Alaskan Way Viaduct Replacement Program Deputy Administrator Matt Preedy. “These closures keep drivers and crews safe while getting the work done each weekend.”

Drivers should plan for increased congestion in and near downtown Seattle. WSDOT recommends leaving early, carpooling or taking transit. Drivers can check traffic conditions before they leave at www.wsdot.wa.gov/traffic. Up-to-the-minute traffic information is also available via the voice-activated, 511 driver information line.
The South Atlantic Street overpass is part of the Alaskan Way Viaduct Replacement Program. Construction on the overpass started last summer and is scheduled for completion by the end of 2013. The overpass will improve mobility by allowing freight haulers and commuters to bypass the rail crossing near the entrance to the Port of Seattle’s Terminal 46.
