124th Avenue Extension Project

The first section of the Willamette Water Supply Program’s new water transmission line will be installed as part of Washington County’s 124th Avenue Extension Project.

Washington County is extending 124th Avenue north from Wilsonville to Tualatin-Sherwood Road to improve regional mobility and provide access to future commercial and industrial lands between Tualatin and Sherwood. The new road extension will include one travel lane in each direction. In addition to the 124th Avenue extension, safety improvements will be made on Tonquin Road and Grahams Ferry Road.
