Traction Project For 526 Ramp to Southbound I-5 Going On Now

June 20, 2015


Editor’s Note: This project was supposed to happen a couple of weeks ago but was postponed to this weekend. So far there have been no apparent issues from the detour. – LD

This ramp leading from the Boeing Freeway (526) to southbound I-5 is notorious for spin outs in the rain.

35 miles per hour is the recommended speed for this curve.

The Washington State Department of Transportation lists the on-ramp from eastbound 526 to southbound I-5 as among the Puget Sound’s slipperiest, with one of the highest percentages of wet weather collisions in Washington State. This weekend they’re doing something about that. Here are details from a press release sent out by WSDOT.

Starting this week, contractor crews working for the Washington State Department of Transportation will begin work on a $300,000 pilot project designed to increase traction on the eastbound State Route 526 on-ramp to southbound Interstate 5 in Everett.

The process, high friction surface treatment, involves attaching a sand-like aggregate to the roadway surface using industrial strength glue. The grittier roadway surface gives tires extra traction when the roadway surface is wet. While this project is the first of its kind for WSDOT in Puget Sound, it has proven successful in many other states across the country.

“It’s no secret that roadways, especially curved ramps, get slippery in the rain,” said WSDOT Transportation Engineer Dina Swires. “We expect to see a dramatic reduction in the number of collisions on both of the ramps for those drivers who overlook the posted advisory speed, misjudge the curves or are just not paying attention.”

In 2014, wet weather was a contributing factor in nearly 74 percent of the crashes on the eastbound State Route 526 on-ramp to I-5 and in 84 percent of the crashes on the 148th Avenue Southeast on-ramp to I-90.

Ramp closure details

  • The eastbound SR 526 ramp to southbound I-5 will be closed from 10 p.m. Friday to 5 a.m. Monday. Everett drivers will be detoured around the closure.
