ARLINGTON – A 10-mile section of northbound and southbound Interstate 5 between Arlington and Conway will soon look and feel very different as work to repair and replace concrete gets underway. Work on the two-year job begins Monday, July 16.

Washington State Department of Transportation contractor crews from Graham Contracting, Ltd. will repair and replace damaged concrete in order to preserve the highway and create a smoother driving surface for the 85,000 vehicles traveling this section of freeway each day.

“Some of this is the original concrete from 1959 when I-5 was extended through the area,” said WSDOT Project Engineer Shane Spahr. “We are replacing nearly 400 concrete panels and grinding an additional 18,000 to eliminate wheel ruts which can collect water and reduce traction.”

Expect lane, ramp and sidewalk closures beginning July 16
During construction, people who travel on I-5 between Arlington and Conway should expect:

  • Infrequent single lane closures during the day with two lanes open in each direction.
  • I-5 reduced to one lane overnight, with the exception of Friday nights.
  • Occasional ramp closures while crews repave 16 on- and off-ramps. No two consecutive ramps will close at the same time.
  • Restricted pedestrian access while crews repair seven sidewalk ramps on State Route 532.
  • Travelers should expect delays of 30 minutes or less.

Please remember to slow down and pay attention near work zones to keep construction crews and drivers safe.

The $21.5 million project is expected to wrap up in spring of 2020.
