69th Avenue bridge at Rock Creek

Project Description


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

The 69th Avenue bridge will be replaced with a wider concrete structure with two travel lanes, bicycle, and pedestrian facilities. The new single-span bridge will be designed to increase safety, protect fish passage and preserve the waterway. Bridge construction will likely require a road closure during construction.


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.
