Safer pavement coming to 46 ramps along I-5, I-205, SR 14 and SR 500

VANCOUVER – More than 40 highway ramps in Clark County will get a facelift starting this month, creating a safer and smoother ride before the rainy season begins. While work is underway, nighttime travelers should plan for ramp closures along Interstate 5, I-205, State Route 14 and SR 500.

Washington State Department of Transportation contractor, Granite Construction, will start work on Monday, Sept. 11 to repave 46 on- and off-ramps throughout Clark County.

The fresh asphalt will create a smoother and safer ride with better traction and new pavement markings will improve lane visibility for drivers.

Improved traction

In addition to smoothing the driving surface, contractor crews will apply a high friction surface treatment on several curved ramps. High friction surfacing is a process that attaches a sand-like aggregate to the roadway using industrial-strength glue. The result is a grittier road surface, giving tires extra traction in the wet weather. WSDOT has applied high friction surface treatments to other curved interchanges and seen a reduction in collisions by up to 80 percent.

“We’re excited to start this important work, which will provide a smoother, safer driving experience for travelers entering and exiting our highways, “said WSDOT Project Engineer Jennifer Darcy. “The improved roadway surface will give drivers better control, resulting in fewer collisions, which will help keep traffic moving within the interchanges, reducing highway congestion.”

Closure details

• Beginning the week of Monday, Sept. 11, travelers may encounter ramp closures throughout Clark County on weekdays and weekends:
  • Weekday lane, ramp and shoulder closures are permitted from 7 p.m. to 5 a.m.
  • Occasional weekend lane, ramp and shoulder closures are permitted from 9 p.m. to 8 a.m.

To minimize delays and reduce congestion for travelers, this work will be completed at night when there’s less traffic.

This $5 million project is scheduled for completion in summer 2024.

As with any highway maintenance and construction project, travelers must exercise caution through the work zone. To keep both road users and road workers safe, travelers are asked to have patience and obey advanced warning signs.
