State Route 99 ramps near Seattle stadiums to close this weekend for work

If  Saturday plans include a trip to SODO - south of downtown Seattle, cross the State Route 99 ramps near the stadiums off the list of route options.

Crews working for contractors building the SR 99 tunnel and the South Atlantic Street overpass will close the on-ramp from South Royal Brougham Way and the off-ramp to South Atlantic Street for much of the weekend. The right lane of southbound SR 99 will also be closed south of downtown Seattle. The ramps and lane will reopen two hours before the kickoff of Sunday’s Seahawks game at CenturyLink Field.
