Drivers traveling through downtown Seattle should expect delays this weekend, this time because of Highway 99 closures for construction and a charity race.
Both directions of Highway 99 between Denny Way and South Spokane Street will close from 6 a.m. to 6 p.m. Saturday and Sunday so crews can inspect the Alaskan Way Viaduct, according to the Washington State Department of Transportation.
Crews will also close both directions of the highway from Valley Street to the south end of the Battery Street Tunnel from 10 p.m. Friday to 6 a.m. Sunday. The closure will allow crews to start building connections to city streets at the north portal of the future Highway 99 tunnel, WSDOT said.
At 6 a.m. Sunday, the closure will extend to the Woodland Park Zoo at North 50th Street for the Hot Chocolate 15/5k race. Participants will be off the road by 11 a.m. The race will also close sections of Elliott and Western avenues as well as streets near the Seattle Center start and finish points.
WSDOT recommends drivers use Interstate 5 as an alternative route, because it will be free of construction closures this weekend.
On Monday morning, drivers should expect congestion on Highway 99 and at the Denny Way on- and off-ramps as drivers get used to the extension of the lane reduction south of Mercer Street. The lane will be reduced until the Highway 99 tunnel opens.
