69th Avenue Bridge at Rock Creek

Project Description

The 69th Avenue bridge has been replaced with a wider concrete structure with two travel lanes, bicycle, and pedestrian facilities for increased safety. The new bridge was designed to protect fish passage and preserve the waterway. Bridge construction requires a road closure during construction.

The previous NE 69th Avenue (formerly 227th Avenue) bridge over Rock Creek was a decaying six-span timber structure built in the 1960s. The bridge was decaying and restricted to one lane of traffic and weight limited to 13 tons as of September 2016. 

Funding Information

This $3.5 million bridge replacement project is funded through the Washington County Road Fund and is in partnership with the city of Hillsboro. The total project cost includes the estimated cost of design, right-of-way and construction and is subject to change.
