Welcome to the project website for the SW 124th Avenue Project:
Tualatin-Sherwood Road - Grahams Ferry Road.

The 124th Avenue project will construct an interim two-lane arterial between Tualatin-Sherwood Road and Grahams Ferry Road. The project will also construct safety improvements on Tonquin Road and Grahams Ferry Road. In addition to the road project, a water transmission line will also be installed as part of the Willamette Water Supply Project (www.ourreliablewater.org). Construction for both projects is scheduled to begin spring 2016.

124th Avenue is identified in the City of Tualatin’s Transportation System Plan (TSP) as a major arterial street and in Metro’s 2035 Regional Transportation Plan (RTP) as a “community street” (Metro Project ID # 10736).

The 124th Avenue Project is a high priority on Washington County’s project improvement list. For information about the project history and progress, please see the Project News Updates page.
