Construction is expected to start Aug. 16 and to end by September 2024.

This project includes installation of a 66-inch diameter section of the Willamette Water Supply Program drinking water transmission pipeline. This partnership reduces cost and traffic impacts.

Construction will be done in four phases; Tualatin-Sherwood and Roy Roger roads and Highway 99W will remain open. 

The $40.6 million project is funded through the County’s Major Streets Transportation Improvement Program (MSTIP) and Willamette Water Supply System reimbursements.
