Looking for real-time travel updates?

Clark County​ 

  • Beginning Monday, Aug. 30, until further notice: Up to two lanes of southbound I-5 between East Fork Lewis River at milepost 18.0 and North Fork Lewis River at milepost 20.0, will close nightly, from 7 p.m. to 7 a.m., for paving and concrete panel replacement work. 
    • At least one lane will remain open throughout the duration of the project.
    • The speed limit is reduced to 55 mph throughout the length the work zone. ​
  • May 2021 through September 2021: Expect daytime delays in downtown Vancouver when traveling on Mill Plain Boulevard (State Route 501) and East 15th Street between Fort Vancouver Way, just west of Interstate 5, and West 26th Avenue near the Port of Vancouver for roadway improvements this summer. Travelers may encounter sidewalk closures in the area.
     
  • Freight travelers who use northbound I-5, will temporarily shift to use the center lane along the northbound span of the Lewis River Bridge about two miles south of Woodland. Shifting large truck traffic to use the center lane of northbound I-5 helps prevent further damage to the bridge deck and extends the usable life of temporary repairs. 

Cowlitz County

  • No scheduled traffic impacts. 

Klickitat County

  • Monday, Sept. 20 to Thursday, Sept. 23: Travelers on both directions of SR 14 about 2 miles east of Bingen should plan for delays of up to 20 minutes, weekdays from 7 a.m. to 5 p.m., for rock scaling and slope stabilization work. 
  • Thursday, Sept. 30: Travelers on both directions of SR 14 about 2 miles east of Bingen, should plan for delays of up to 20 minutes, weekdays from 7 a.m. to 5 p.m., for rock scaling and slope stabilization work.

    • Note: Crews will close the highway at the top of each hour and reopen the highway at 45 minutes past the hour to allow traffic in both directions to clear. These extended closures allow crews to complete more work, shortening the project duration and ensuring the safety of travelers below.

Safety tips for traveling through work zones

  • Drive the posted construction speed limits - it's the law! Traffic fines are doubled in work zones. 
  • Pay attention - driver inattention is the number one cause of work zone accidents.
  • Leave room between you and the car ahead of you - most work zone accidents involve someone running into the car ahead of them.
  • Drive defensively - be aware of what is happening around you.
  • Merge into the proper lane before you reach the work zone.
  • Don't use cell phones or adjust your radio while driving.
  • Avoid work zones by using alternate routes.
