Additional overnight lane closures begin Monday

SEATTLE – Drivers should expect closures of State Route 99/Aurora Avenue North beginning Friday evening, Dec. 18. Crews will close the highway between the south end of the Battery Street Tunnel and Valley Street, but will reopen it in time for basketball fans to get to the Gonzaga game against Tennessee at Key Arena on Saturday.

During the lane closures, contractor crews working for the Washington State Department of Transportation will start building the permanent median between northbound and southbound lanes along the new section of SR 99/Aurora Avenue North that opened in August.

Closure details and transit changes

  • Northbound SR 99 lanes: Closed from 9 p.m. Friday, Dec. 18 to 5 p.m. Saturday, Dec. 19.
  • Southbound SR 99 lanes: Closed from 9 p.m. Friday, Dec. 18 to 7 a.m. Saturday, Dec. 19. One southbound lane will remain closed until 1 p.m. Saturday, Dec. 19.
  • Metro Transit changes: routes 5, 16, 82 and RapidRide E Line are scheduled to be rerouted around the construction closures and travel on Dexter Avenue North. Details will be posted on Metro’s service advisories.

Lane closures Dec. 14-22
In addition, crews installing a variable message sign may close one southbound lane of SR 99 between Roy and Mercer streets from 8 p.m. to 6 a.m. nightly beginning Monday, Dec. 14 through Thursday, Dec. 17; and Monday, Dec. 21 through Tuesday, Dec. 22.

Looking ahead
In mid-January 2016, work to build sign foundations for the new SR 99 tunnel will require lane closures along a one-mile stretch of SR 99/Aurora Avenue North between Highland Drive and Raye Street, just south of the Aurora Bridge.

One lane in each direction will be closed around the clock for approximately seven weeks. An additional lane will close at night and some weekends. At least one lane will remain open at all times during construction.

WSDOT will share additional information prior to those lane closures. Drivers can also plan ahead by checking for major traffic impacts on all state highways. Real-time information is available using WSDOT’s travel tools or SDOT’s traveler’s information web page.
