Nighttime ramp closures begin next week on Sept. 11

SEATTLE – Juggling takes careful coordination, especially when it involves multiple construction zones along a very busy stretch of highway.

As major weekend work on northbound Interstate 5 south of Seattle winds down, the next phase of pavement rehabilitation efforts on the region’s main north-south route is about to ramp up in the heart of Seattle.

Washington State Department of Transportation contractor crews will begin paving several northbound I-5 on- and off-ramps in Seattle starting Monday, Sept. 11, through the end of the month. This work is part of the second, major northbound I-5 restoration project between Martin Luther King Jr. Way and Northeast Ravenna Boulevard that will improve 13 miles of roadway. There are a total of 23 ramps that will be repaved as part of this project, and crews will look to get a head start on what will be a big job in 2018.

All of the work on this project, through the tail end of 2017, will take place at night and in coordination with the nearby and ongoing northbound I-5 South 260th Street to Duwamish River preservation project.

In order to give crews south of Seattle the time and space to complete their three remaining weekends of major work, the 16 weekend-long lane closures needed for this second phase of #ReviveI5 will not start until 2018.

“Between the weather and large special events, our available weekends are limited,” said WSDOT Northwest Regional Administrator Lorena Eng. “On top of that, our engineers must make sure the two projects are coordinated to avoid conflicts, and then use extreme finesse in timing the weekends around other roadwork closures or changes to the transit system. We are not taking this work – and its effect on the 100,000 daily vehicles that use this highway – lightly.”

Much of this 22-mile stretch of northbound I-5 is more than 50 years old. Restoration work includes concrete panel and expansion joint replacement, pavement grinding and asphalt repaving. These projects are part of a years-long effort to preserve I-5 through King County.

Martin Luther King Jr. Way to Northeast Ravenna Boulevard project details

This 13-mile section of northbound I-5 is mostly elevated freeway, with expansion joints connecting concrete highway sections. From 2018 to 2019, contractor crews from Guy F. Atkinson Construction, LLC will:

  • Replace 37 expansion joints between South Boeing Access Road and Northeast 45th Street
  • Replace all concrete panels just north of the West Seattle Bridge to near the express lanes ramp, except for bridges
  • Grind concrete sections to remove ruts
  • Replace a total of four bridge approach slabs on three bridges
  • Repave 23 on- and off-ramps

South 260th Street to Duwamish River project update

By fall 2018, contractor crews from Gary Merlino Construction will complete 8.9 miles of northbound I-5 work similar to what has been done on southbound I-5 between the Duwamish River and Federal Way. So far, crews have replaced three expansion joints and about 225 concrete panels, along with four miles of repaving from SR 516 to South 170th Street. Crew must still:

  • Replace five expansion joints at Interurban Avenue South
  • Replace eight expansion joints at the Duwamish River Bridge
  • Replace about 265 more broken concrete panels
  • Grind concrete sections to remove ruts

This project requires three more weekend-long lane reductions:

  • Friday, Sept. 8, to Monday, Sept. 11
  • Friday, Sept. 29, to Monday, Oct. 2
  • Friday, Oct. 13, to Monday, Oct. 16

Nine weekends with lane reductions occurred earlier this summer.

I-5 work in Tacoma

There are additional construction zones on I-5 for the Tacoma/Pierce County HOV Program. Closures for these projects are also carefully coordinated with major work in King County.
