I-5 - NB S 260th to Duwamish River Bridge - Concrete Pavement Rehab and ADA - Alternative routes

NB I-5 alternate routes
During weekend-long lane reductions on northbound I-5 in SeaTac and Tukwila, drivers should use alternatives like transit, carpooling or alternate routes shown above. The project requires a total of 10 weekend-long lane reductions. Three of the six scheduled weekends for paving from SR 516 in SeaTac to South 170th Street in Tukwila are finished. The remaining weekends are:

  • July 7-10 and 14-17
  • Aug. 11-14

The other four weekend-long lane reductions to replace expansion joints on northbound I-5 at Interurban Avenue and the Duwamish River Bridge have yet to be scheduled. Two will be in late summer or fall 2017. Two others will be in the first half of 2018.
