Cornelius Pass Road (Frances to Wilkins)

Washington County and the City of Hillsboro worked cooperatively to improve Cornelius Pass Road between Frances Street to just south of Wilkins Street. 

Reason for Improvements

Due to growing residential and commercial development in the area, the traffic load continues to increase. The improvements will reduce congestion and improve safety.

  • Added two through lanes in each direction at the Cornelius Pass and Quatama intersection
