Tualatin-Sherwood Road (Langer Farms Parkway to Teton Avenue)

Tualatin-Sherwood Road will be improved between Teton Avenue and Langer Farms Parkway. This project includes installation of a Willamette Water Supply pipeline. Construction began in 2022.

Tualatin-Sherwood Road, between Teton Avenue and Langer Farms Parkway, is a major intersection with a lot of traffic. We are widening it to improve both current and future traffic.

The project includes:

  • Five travel lanes (two travel lanes in each direction and a center-turn lane)
  • Bicycle and pedestrian facilities on both sides of the road
  • Storm drainage upgrades and water treatment facilities
  • Street lights

We are partnering on this project with the Willamette Water Supply System (WWSS) new 66-inch drinking water pipeline installation.
