Cornell Road and 25th Avenue Intersection

Cornell Road and 25th Avenue is a heavily used intersection near the Hillsboro Airport.

We are widening intersection to keep up with people using these roads. The project will improve safety for pedestrians, cyclists and drivers.

This project includes:

  • Adding dedicated turn lanes from southbound 25th Avenue onto Cornell Road
  • Adding bicycle lanes
  • Updating street lights and traffic signals

A northbound lane-closure on 25th Avenue is tentatively planned for late May/early June.

Construction start: December 13, 2024
Construction finish (expected): September 2025

Update

2/7/2024: Expect intermittent lane closures 9 a.m.-3:30 p.m. weekdays on Cornell Road and 25th Avenue within 1500 feet of the intersection.

Expect delays.

We will close 25th Avenue northbound for 12 days of construction, tentatively beginning May 23.
