For Immediate Release: Wednesday, July 08, 2015

Sponsored by: Department of Land Use and Transportation, Capital Project Services Division

Cornelius Pass Road Project Vicinity MapConstruction on Cornelius Pass Road between Cornell Road and U.S. 26 is starting Monday, July 13.  

Washington County's contractor Kerr Contractors Oregon, Inc., will begin by mobilizing equipment and traffic control devices. Construction will then start on the east side of Cornelius Pass Road. Project completion is scheduled for December 2016.

Project Details

The project will widen Cornelius Pass Road between Cornell Road and U.S. 26 to three lanes in each direction with dedicated turn lanes at several intersections. Additional improvements include sidewalks on both sides of the road, a buffered bike lane on the west side, and a two-way bike path on the east side along the abandoned railroad line. Additional street lighting and wiring for an interconnected traffic signal system will also be installed between U.S. 26 and Aloclek Drive.

Traffic Impacts

Travelers should expect delays or use alternate routes for the duration of the project. Brookwood Parkway and 185th Avenue are the suggested alternate routes for through traffic, including truck traffic. Please note that Brookwood Parkway will also be under construction starting this fall, but work will be performed only at night.

Construction on Cornelius Pass Road will occur between 7 a.m. and 7 p.m. Monday through Friday, with lane restrictions from 8:30 a.m. to 4 p.m. each day. Flaggers will move traffic safely through the work zone. On some occasions work will also occur on Saturdays and at night.

Additional Information

This project is funded through private development, 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.
