Washington County Cornelius Pass-Old Corneilus Pass, Germantown Improvements, OR

Improves intersection safety and reduces traffic delays.

Quick Facts

  • Washington County identified the need for intersection improvements at Cornelius Pass Road/Old Cornelius Pass Road and the intersections adjacent to it, due to the existing traffic delay, long queues along the side streets, and safety concerns

  • DKS installed a traffic signal at Cornelius Pass Road/Old Cornelius Pass Road with the addition of a dedicated left-turn lane for northbound traffic

  • Project also included making the Germanton/Cornelius Pass intersection a right-in and left-in only movement in order to divert everyone to the signal where it is the safer location to make left turn movements


  • Minimizes traffic delays and queues by allowing more opportunities for the traffic on the side streets to turn on to the main line

  • Improves safety for vehicles as they are protected by the signal to safely make a left turn or through movements

  • Improves safety for pedestrians as they now have ADA ramps and pushbutton to safely cross the street

  • Improved lighting at the intersection brings more awareness to the intersection and improves safety

Our Work
