Drivers should plan for backups on SR 99, choose alternate routes

SEATTLE – From SODO to Fremont, much of State Route 99 in Seattle will be closed this weekend while crews inspect and reinforce the Alaskan Way Viaduct and upgrade expansion joints on the Aurora Bridge.

The Washington State Department of Transportation coordinated closure schedules to keep traffic moving before and after Sunday’s 6 p.m. match between Sounders FC and the Portland Timbers at CenturyLink Field.

“This critical work on the viaduct and the Aurora Bridge requires major closures, but more than 60,000 fans need to get to the match and back home,” said WSDOT Alaskan Way Viaduct Replacement Program Deputy Administrator Matt Preedy. “We scheduled the work so crews would not disrupt traffic before and after the game.”

Alaskan Way Viaduct closures

  • Both directions of SR 99 between the north end of the Battery Street Tunnel and the West Seattle Bridge will close at 6 a.m. Saturday, Oct. 6.
  • SR 99 will reopen by 4 p.m. Sunday, Oct. 7, two hours before the start of the Sounders FC match with Portland at CenturyLink Field.

During the closure crews will conduct the viaduct’s semiannual inspection and do routine maintenance. WSDOT will release preliminary inspection results on Monday, Oct. 22.

SR 99 tunnel crews will also use the closure to continue placing reinforcing fiber wrap on the viaduct between South Washington and Columbia streets. The fiber wrap will protect the viaduct when the world’s largest diameter tunnel boring machine passes beneath the structure in late 2013.

Southbound Aurora Bridge lane closures
Further north on SR 99, crews will close lanes on the Aurora Bridge to replace and repair three expansion joints. The expansion joints run the width of the bridge, allowing sections to expand and contract. This flexibility helps bridges better withstand earthquakes. Crews are fixing the expansion joints as part of a seismic retrofit of the Aurora Bridge.

  • Southbound SR 99 will be reduced to one lane across the bridge between 9 p.m. Friday, Oct. 5, and 2 p.m. Sunday, Oct. 7.
  • At 2 p.m. Sunday, crews will open a second southbound bridge lane.
  • At 3 p.m. Sunday, all southbound bridge lanes will be open to accommodate fans heading to the Sounders FC match.
  • At 7 p.m. Sunday, southbound SR 99 will again be reduced to one lane across the bridge. All southbound lanes will reopen by 5 a.m. Monday, Oct.8.

Northbound Aurora Bridge lane closures

  • Northbound SR 99 will be reduced to one lane across the bridge between 9 p.m. Friday, Oct. 5, and 7 p.m. Sunday, Oct. 7.
  • At 7 p.m. Sunday, crews will open all northbound bridge lanes to accommodate traffic leaving the Sounders FC match.
  • At 10 p.m. Sunday, northbound SR 99 will again be reduced to one lane across the bridge. All northbound lanes will reopen by 5 a.m. Monday, Oct. 8.

Drivers should plan for increased congestion in and near downtown Seattle. WSDOT recommends leaving early, carpooling or taking transit.
