Cornelius Pass Road connects Hillsboro and South Hillsboro. We will widen Cornelius Pass Road between Frances Street and Tualatin Valley Highway (OR-8) to match the road north and south of the project area, and will also add a dedicated right-turn lane from westbound Tualatin Valley Highway to northbound Cornelius Pass Road.

We are coordinating the Willamette Water Supply Program (WWSP) to construct their drinking-water pipeline with the road project. Visit South Hillsboro for more details about development and roads south of Tualatin Valley Highway.

Construction start (expected): March 2022
Construction finish (expected): December 2023

Update 7/22/2022: Some waterline work is being delayed due to supply chain issues.
