Boones Ferry Road Culvert Project Update: October 22, 2018
Construction Delayed until February 2020

The Boones Ferry Road Culvert Replacement project construction has been delayed. The project was scheduled to begin construction in 2019; however, it is now expected to begin in February 2020. Limited steel availability has increased the project budget by $2.5 million.  Project partners are now working together to identify additional funding for the project.

The SW Boones Ferry Road culvert has been identified by the City of Portland as one of two major fish passage barriers on the mainstem of Tryon Creek.  The project will remove an undersized 60-inch, 140-foot-long corrugated metal pipe culvert that carries Tryon Creek under SW Boones Ferry Road. It will be replaced with a new single span steel girder bridge that will allow fish passage and provide a safer crossing for pedestrians and wildlife. The existing culvert restricts stream flow and does not allow fish to access Upper Tryon Creek and Arnold Creek upstream of SW Boones Ferry Road. This project also includes improvements to both Tryon and Arnold Creeks upstream of the culvert which will expand upstream habitat and provide significant benefits to fish that use the streams.

As the design for this project has progressed, steel prices have increased more than 40% over the last year. Environmental Services needs to evaluate the current construction costs and work with project partners to meet the project budget needs. Over the next few months, Environmental Services will be working with project partners to identify additional resources.

Environmental Services looks forward to completing design in December 2018 and moving into construction on this fish, wildlife, and trail passage partnership in February 2020.
