Project area map for Boones Ferry


The Boones Ferry Road Culvert project is moving forward again and is slated for construction in the spring of 2020. This project was put on hold in early 2019 due to an increase in steel prices.  Environmental Services’ project team and bureau leaders have secured the necessary funding to allow the project to proceed. 


A contractor is expected to be selected in early 2020.  Initial work clearing brush and removing trees from the work area will occur in February and March of 2020.  This work is being coordinated to avoid interfering with the bird nesting season.  Major construction activities are expected to begin in the the early summer of 2020. Work will be completed in late 2020.



TRAFFIC DETOURBoones Ferry Detour route Map

In order to construct the new bridge, SW Boones Ferry Road will be closed for up to seven months. Detailed information on the start date and detour route will be publicized this winter.  The Portland Bureau of Transportation has provided a traffic control plan and a designated detour route for auto traffic during the construction of the new bridge.  Please see the detour map for information on the planned detour route.



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.  The project is partially funded by a Metro Nature in the Neighborhoods Grant, and will help protect water quality and the environment.

culvert under Boones Ferry Road

The project aims to:

  • Allow fish to pass into Upper Tryon Creek and Arnold Creek upstream of Boones Ferry Road;
  • Improve stream flow;
  • Install large wood and rock to protect fish habitat, reduce erosion and improve water quality;
  • Protect an exposed sewer pipe on Tryon Creek upstream of the culvert;
  • Provide pedestrian and wildlife passage through the new bridge;
  • Provide trail connectivity to the Tryon Creek State Natural Area North Creek Trailhead;
  • Incorporate trail enhancements to add a trail under the bridge, stairs to the roadway, and a widened shoulder to the North Creek trailhead.
