A wider, safer corridor will help accommodate increasing traffic volumes.

April 2017

  • June 27, 2016 - All lanes of the new wider, safer SR 502 open to traffic.
  • March 2016 - A new signal at NE 92nd Ave. will improve traffic flow on SR 502 and allow U-turns for all vehicles, including truck-trailer combinations.
  • We awarded this contract to Rotschy, Inc. of Vancouver, WA on March, 2014

This project widens State Route 502 from two to four lanes from I-5 east into the city of Battle Ground. Median barrier will also be installed to help reduce the severity of collisions along the corridor.

Additionally, crews will construct 10-foot-wide shoulders for pedestrians and bicyclists along both sides of SR 502 for the entire length of the corridor.
Sidewalks and bike lanes will be built in the commercially zoned area near Dollars Corner, located at the intersection of SR 502 and NE 72nd Avenue.

Why is WSDOT widening State Route 502?
Central Clark County has been growing for decades. Traffic on SR 502 is expected to double in the next 20 years, and the highway needs to be wider and safer to support this increase in traffic and reduce the risk of collisions.

The End Result
Safer, faster trips on SR 502 between I-5 and Battle Ground. SR 502 will be a four-lane highway with median barrier and 10-foot shoulders for bicycle and pedestrian travel. Traffic signals will help drivers more safely access or cross SR 502 at NE 29th, 50th, 72nd and 92nd avenues.

Project Benefits

  • Congestion Relief: Improves mobility and provides better access from I-5 to the city of Battle Ground.
  • Safety: Adds two additional lanes and controls access onto and off of the highway. Median barrier will help reduce the severity of collisions.
