Background on Cornelius Pass Road/Frances Road Waterline Break
On the morning of Tuesday, March 25, 2025, a waterline break occurred at the SE Cornelius Pass Road and SE Frances Street intersection in Hillsboro. The leak caused a sink hole in the intersection and damaged a 10-inch City of Hillsboro waterline. This was a leak on an 18-inch pipeline, part of the Willamette Water Supply System PLW_1.2 project. The PLW_1.2 pipeline was built in conjunction with Washington County’s Cornelius Pass Road project between Frances Street and Tualatin Valley Highway.
A temporary repair was completed on March 28, 2025 to reopen the intersection. The permanent pipeline repair and road repair are anticipated to take place between mid-June and early September to minimize impacts to R.A. Brown Middle School.
Development of South Hillsboro, a 1,400-acre mixed-use community, requires coordination between multiple agencies and infrastructure projects. The Willamette Water Supply Program (WWSP) coordinated with the City of Hillsboro, Washington County, and private developers to install the portion of the Willamette Water Supply pipeline that will serve the City of Hillsboro. All approximately four miles of the Willamette Water Supply South Hillsboro pipeline have been installed, most of it in coordination with South Hillsboro projects.
Coordinating construction of the pipeline with Cornelius Pass Road improvements north of TV Highway and the Cornelius Pass Road extension south of TV Highway saves money, reduces community and neighborhood impacts, and minimizes the need for multiple construction projects.
