Cornelius Pass Road (Cornell to U.S. 26)

About the project:

Cornelius Pass Road is a heavily used north/south arterial roadway. It is an important commuter and truck route connecting Highway 30 in Multnomah County to Tualatin Valley Highway in southern Hillsboro. Cornelius Pass Road between Cornell Road and U.S. 26 carries approximately 40,000 vehicles per day. The current roadway is not adequate for existing traffic and projected traffic growth in the area.

This project will widen Cornelius Pass Road between Cornell Road and U.S. 26 to three lanes in each direction with a center median and dedicated turn lanes at several intersections, including U.S. 26.

Additional improvements include:

  • sidewalks on both sides of the roadway
  • buffered bike lane on the west side of the road
  • separated two-way bike path on the east side
  • intersection upgrades
  • additional street lighting (south to Aloclek Drive)

The $18.3 million project is funded through a combination of sources including private development, phase 3d of the County's Major Streets Transportation Improvement Program (MSTIP), State of Oregon Immediate Opportunity Funds (IOF) and the City of Hillsboro's Transportation Development Tax and Traffic Impact Fee programs.
