FULL Closure of Northbound I-5 This Weekend -- Expect Heavy Congestion

July 11, 2018 - Summer construction season is underway and this this weekend, WSDOT continues its Northbound I-5 repaving work with a FULL closure in south Seattle slated to start at 8:00pm on Friday, July 13, and end at 5:00am on Monday, July 16 (weather permitting).

Vehicles detouring to Northbound I-405 are expected to generate additional traffic on Westbound I-90 across Mercer Island. VERY extensive regional congestion is expected! Island residents wishing to reach Seattle should allow *plenty* of extra time for their journey.

Ramp impact summary:
  • Westbound I-90 to NB I-5 will remain OPEN, but congested
  • Westbound I-90 to SB I-5 will be OPEN, slowdowns likely
  • Northbound I-5 to EB I-90 will be CLOSED
  • Southbound I-5 to EB I-90 will be OPEN
Full details, and closure map, available here.
