The Oregon Department of Transportation (ODOT) is replacing the Cornelius Pass Road bridge over Rock Creek in cooperation with Washington County. 

The bridge was built in 1946 and not designed to handle freight traffic. We are replacing it with a single-span bridge with two vehicle lanes and wide shoulders.

Construction start (expected): Summer 2023
Construction finish (expected): December 2023

Update 1/24/2022: The design consultant is beginning to design the new bridge.
