Needs & benefits

Beginning in summer 2021, contractor crews will rehabilitate a nearly two mile stretch of southbound Interstate 5, just south of Woodland, WA between milepost 18.28 and 20.0, in Clark county. 

Concrete panel replacement
Crews will replace concrete panels throughout the length of the project. These panels are cracked beyond repair.

Asphalt nearing the end of its lifespan will be removed. Crews will grind the top layer of asphalt off the southbound left lane of the interstate and remove existing rumble strips to accomodate construction staging needs. This will create a new, safer driving surface.

Why is WSDOT repaving this stretch of I-5?
Sections of the interstate are showing signs of wear and tear. There are cracks, ruts and potholes in many places along the highway. The work needs to be done to improve the structural integrity of the roadway.

This $7.6 million project will extend the life of the roadway and provide a smoother surface and safer ride for drivers.

I-5 is the most significant freight freeway on the West Coast, linking markets in Canada, the United States and Mexico and is critical to the regional, state and national economy. It is the busiest commuter roadway in western Washington.

The End Result
Rehabilitating this stretch of I-5 extends the life of the interstate and preserves an important commuter and freight corridor for many years to come. 

Project Benefits

  • Preservation – Repaving this section of I-5 will improve the surface of the roadway and extend the life of the highway. 
  • Safety – Removing ruts and cracks will produce a smoother highway surface, creating a safer ride for drivers. 
  • Economic – Repaving this section of I-5 will reduce the need for costly emergency repairs and maintenance work.


Once construction begins, travelers will encounter nighttime, single lane and double lane closures with rolling slowdowns and a temporary speed limit reduction from 70 mph to 55 mph, within the work zone. This speed limit reduction will remain in place throughout construction.  

Additionally, beginning in July, contractor crews will have a single lane of southbound I-5 closed, around-the-clock, for 21 consecutive days. This single lane closure may cause significant delays and travelers are reminded to plan ahead when traveling through this area.  


  • April 2021: Project goes to competitive bid 
  • June/July 2021: Construction scheduled to begin
  • Fall 2021: Project scheduled for completion 


The estimated cost of this project is approximately $7.620 million.
