Special events will add to congestion unless drivers have a game plan

SEATTLE – Seattle-area drivers may wish they could turn back time unless they plan ahead for a weekend packed with major road closures, baseball games, a Cher concert and a downtown parade.

On Friday, June 27, contractors working for the Washington State Department of Transportation will begin weekend-long closures of the State Route 520 floating bridge and two lanes of northbound Interstate 5 at the West Seattle Freeway.

The SR 520 floating bridge will undergo its annual maintenance inspection. Contractor crews on the SR 520 Bridge Replacement and HOV Program will also continue to pour concrete for the roadway deck of the new West Connection Bridge and outfit the new eastbound SR 520 lanes with another 10,000 tons of asphalt as part of the Eastside Transit and HOV Project.

The work on I-5 to replace 33 aging bridge expansion joints reaches an important milestone this weekend: Crews will replace the left half of six expansion joints and wrap up the bulk of the work. Around-the-clock closures will no longer be needed for this work after this weekend, although some overnight lane closures might still be necessary.

Closure details (all roadways will open by 5 a.m. Monday, June 30)

  • 10 p.m. Friday: The two left lanes of northbound I-5 at the West Seattle Freeway close to replace the left half of seven aging expansion joints. No ramps will be closed.
  • 11 p.m. Friday: Both directions of the SR 520 floating bridge will be closed between Montlake Boulevard and Interstate 405.
  • 11 p.m. Friday: The intersection of Northup Way and 108th Avenue Northeast in Bellevue will be closed for improvements.

Special events
Local events this weekend will add to travel times and traffic congestion:

  • Friday, June 27: The Mariners open a three-game series at Safeco Field against Cleveland at 7:10 p.m.
  • Saturday, June 28: The second game of the Mariners/Indians series begins at 7:10 p.m., and a Cher concert at KeyArena begins at 8 p.m.
  • Sunday, June 29: The Seattle Pride Parade will close the southbound I-5 exit-only ramp to Union Street from 10 a.m. until 3:30 p.m., and the Mariners/Indians series wraps up beginning at 1:10 p.m.

Know before you go
Travelers should plan ahead for delays and congestion. On Saturday and Sunday, traffic will begin increasing around 8 a.m. and likely remain heavy until around 10 p.m. WSDOT needs drivers’ help to keep traffic moving smoothly through the weekend:

  • Allow extra time to reach their destination.
  • Travel outside of peak hours and delay or reschedule discretionary trips.
  • Use alternate routes into Seattle, including State Routes 599 and 99.
  • Take I-405 if traveling north of Seattle.
  • Choose an alternative travel mode, such as public transportation (transit, ferry, light rail or commuter rail), bicycling or carpooling.

Travelers can hit a home run before hitting the road by using WSDOT’s travel tools and resources to create a commuting strategy:
