Northbound state Route 99 lane and on-ramp closed this weekend near Seattle’s stadiums | WSDOT

Construction on the SODO on-ramp to northbound State Route 99 will require several traffic closures near Seattle’s stadiums this weekend.

Fans heading to Saturday’s Sounders FC match at CenturyLink Field should not be alarmed. Crews scheduled a break in the closures to ease traffic before and after the match.

Closure details – Friday, March 14 – Monday, March 17

  • The South Royal Brougham Way on-ramp to northbound SR 99 will be closed from 9 p.m. Friday to 3 p.m. Saturday.
  • Crews will temporarily reopen the on-ramp at 3 p.m. Saturday to keep traffic moving after the Sounders FC match at nearby CenturyLink Field. The ramp will close again at 5 p.m. and remain closed until 5 a.m. Monday.
  • The right lane of southbound First Avenue South will be closed from Railroad Way South to just north of South Royal Brougham Way from 9 p.m. Friday to 11 a.m. Saturday.
  • Crews will temporarily reopen the lane on First Avenue South at 11:30 a.m. Saturday to help move traffic before and after the Sounders match. The lane will close again at 5 p.m. and remain closed until 5 a.m. Monday.
  • The right lane of northbound SR 99 will be closed at South Royal Brougham Way from 9 p.m. Friday to 5 a.m. Monday.

The closures are part of a series of changes to the routing of SR 99 lanes and ramps around the SR 99 tunnel construction zone west of the stadiums. This weekend crews working for Seattle Tunnel Partners and WSDOT will complete work to move the South Royal Brougham on-ramp to northbound SR 99 closer to First Avenue South.

Drivers will begin using the relocated ramp Monday morning. This is the first step in a major traffic shift for the four-lane bypass that takes traffic around the SR 99 tunnel construction zone.

By this summer the bypass will split in two, with northbound SR 99 moving east and southbound SR 99 moving west. The traffic shift will provide space between both directions of the bypass for construction of lanes and ramps into and out of the SR 99 tunnel.
