Looking for real-time travel updates?

Clark County

  • Beginning at 8 p.m., Thursday, June 17 and continuing through 5 a.m., Friday, June 18, travelers within the SR 500/Northeast 117th Avenue and Northeast 65th Street intersection, will be flagged through area, while crews work to install new signing and striping and perform signal work.
  • Please use an alternate route when crews close the Washington Street and Main Street intersections with Mill Plain Boulevard (SR 501) in downtown Vancouver beginning at 10 p.m. Friday June 25 until 4 a.m. Monday June 28 for roadway excavation, paving and striping work.
  • May 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. 
  • 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

  • Beginning at 6:30 a.m., Saturday, June 19 and continuing through 5 p.m., travelers on both directions of SR 504, between the Toutle Lake School at milepost 10.25 and the Johnston Ridge Observatory at the end of the SR 504 route, should slow down and watch for bicyclists who will be traveling within the shoulders for the Tour de Blast 2021 bike ride event.

Safety tips for traveling through 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.
