Five consecutive weekends of lane closures to #ReviveI5

by Tom Pearce

Friday, June 16, marks the start of five consecutive weekends of pavement improvement work on northbound I-5 between SR 516 in SeaTac and the Southcenter area.

As we continue to #ReviveI5, our contractor crews will reduce northbound I-5 to two lanes during the following weekends:
  • June 16-19
  • June 23-26
  • June 30-July 3
  • July 7-10
  • July 14-17 

Expect major backups
Drivers should prepare for lengthy delays during each weekend. During the first weekend of work in June, we saw backups reach six miles at one point. Your best chance to avoid major delays is to plan ahead:
There are several alternate routes to use instead of northbound I-5.
Viva la differencé
This weekend we’ll do crack, seat and overlay work on the left lanes, with two lanes open on the right. We’ll also remove more than 300 feet of concrete panels at four separate locations and replace them with asphalt. Working on the right lanes means the on- and off-ramps at South 188th Street will be open. The SR 516 on-ramps and the South 200th Street on- and off-ramps to I-5 will be closed.

Crews need to remove sections of concrete panels the length of a football field, then replace them with asphalt, to create smooth transitions between the concrete and asphalt.
Making changes
We appreciate the feedback many of you shared with us after our first weekend of work. We received concerns about the lack of signs on some alternate routes, particularly near the South 200th Street/Military Road on- and off-ramps. We put out more signs during the first weekend, and we’ll have better signage throughout the rest of our work this summer.

Why weekends?
We hear that question every time we do a major project that disrupts the weekend. Our contractor crews are doing most of the work during overnight lane closures throughout the week.

It takes a couple of days to break the old concrete, compact it and repave asphalt over the top of it.

However, some of the work simply takes too long to do during overnight lane closures. Crack, seat and overlay work is a three-step process. An overnight shift doesn’t provide enough time to complete the needed steps.

It will be the same later this year and in the first half of 2018 when we replace expansion joints at Interurban Avenue and the Duwamish River – we need more than 50 straight hours to do that work.

We understand all of these lane closures are inconvenient. However, I-5 is the main artery of our region and we need to preserve it. We are confident that a little short-term pain will provide decades of smoother travel. Hang in there! We appreciate your patience!
