Paving on northbound I-5 in SeaTac, expansion joint replacement in Tukwila and guardrail work on SR 509 in Burien

SEATAC – Three more weekends of lane reductions on northbound Interstate 5 between Kent and Tukwila are scheduled this month, along with three weekends that will reduce both directions of State Route 509 to a single lane in Burien.

Contractor crews working for the Washington State Department of Transportation will be hard at work to #ReviveI5 and improve SR 509:

  • Aug. 11-14: Northbound I-5 paving and SR 509 guardrail replacement and paving.
  • Aug. 18-21 and 25-28: Replace expansion joints on northbound I-5.
  • Sept. 8-11 and 15-18: Both directions SR 509 guardrail replacement and paving.

Northbound I-5 in SeaTac, Tukwila

The weekend of Aug. 11-14, three lanes will close to pave the final layer of asphalt on northbound I-5 from SR 516 in SeaTac to South 170th Street in Tukwila. The weekends of Aug. 18-21 and 25-28, three lanes will close for expansion joint replacement at the Duwamish River Bridge in Tukwila.

  • Lane closures will begin at 8 p.m. each Friday. By 10 p.m., northbound I-5 will reduce to two lanes until 5 a.m. each Monday. All work is weather-dependent.
  • The final two weekends of lane reductions, to replace expansion joints at Interurban Avenue, have yet to be scheduled.

Guardrail and paving on SR 509

The left lane in both directions of SR 509 in Burien will close Aug. 11-14, Sept. 8-11 and 15-18 for guardrail repair and replacement and paving.

Lanes will close at 7 p.m. each Friday and reopen at 6 a.m. each Monday. The paving work is weather-dependent.

Plan ahead

Each day more than 100,000 vehicles travel northbound I-5 between Kent and Tukwila, and up to 30,000 use SR 509 in Burien. During the weekend-long lane reductions, drivers can help ease congestion by:

  • Using bus or light rail service.
  • Carpooling.
  • Scheduling trips early or late in the day.

Using alternative routes like I-405, or state routes 99 and 167.
