U.S. 30 (NW St. Helens Road) at Cornelius Pass Road Intersection Safety Improvement Project

Current Status

Construction began in May 2013 and will be complete in fall 2013.

During construction, motorists can expect:

  • Daytime and nighttime lane closures on Cornelius Pass Road with flaggers directing traffic and up to 20-minute delays
  • Work will occur primarily on weekdays
  • No lane closures during morning and afternoon rush hours, during the day on weekends or on holidays.
  • The signal timing at Cornelius Pass and U.S. 30 will not be at pre-construction intervals until project completion. A new traffic signal, and activating signal detection "loops", will be installed as part of the project.

Project Need
The intersection of U.S. 30 (NW St. Helens Road) and NW Cornelius Pass Road has been identified as one of the top locations in need of safety improvements in Oregon. The relatively high number of crashes at this location tend to be rear-end collisions, most of which involve vehicles traveling east on U.S. 30 or south on Cornelius Pass Road.
Project Description

The U.S. 30 Cornelius Pass Road intersection project will improve the right turn from US 30 east to Cornelius Pass Road south by adding a standard right-turn lane. The approach of Cornelius Pass Road north will be widened at U.S. 30 to include separate left- and right-turn pockets. Signals and signing also will be upgraded.

Proposed project elements include:  
  • Widening and extending the right-turn lane from U.S. 30 east to Cornelius Pass Road
  • Widening Cornelius Pass Road to add dedicated right- and left-turn lanes onto U.S. 30
  • Moving a private residential driveway farther west of the intersection
  • Sign and signal improvements
  • Bike shoulder and a pedestrian island at the intersection 
  • Water quality treatment for added roadway surface
