The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency.

City of Portland Environmental Services—your sewer and stormwater utility—is beginning construction of a new bridge on SW Boones Ferry Road where it crosses Tryon Creek. The new bridge will improve water flows by replacing an existing small culvert. This culvert cannot handle large flows of water during storms, and it blocks fish and wildlife. The SW Boones Ferry Bridge & Restoration Project will create and restore important connections for fish, wildlife, and people. It will connect trails and pedestrian facilities in the area, help reduce flooding risk, and restore important habitat.

Project Schedule

Our contractor, MJ Hughes Construction, will begin major construction activities on March 30, 2020. During construction, SW Boones Ferry Road, between SW Arnold Street and SW Comus Court will be closed. Construction and the road closure will last up to seven months.

In preparation for the road closure, crews will install electronic reader boards and signs to warn the public of the upcoming closure and direct commuters of the recommended detour route. Crews will also continue to conduct preconstruction activities. For more information on preconstruction activities, visit

SW Boones Ferry Road Closing On March 30, 2020

Starting March 30, 2020 and lasting for up to seven months, SW Boones Ferry Road will be completely closed from SW Arnold to SW Comus Court.  You can read more details about the road closure here.

In order to build the new bridge, crews will need to completely excavate a large section of Boones Ferry Road. SW Boones Ferry Road will be COMPLETELY closed to all traffic, including for people driving, walking, or biking. Electronic reader boards and signage will be placed ahead of time to warn travelers of the upcoming closure and to guide people to the recommended detour route. Flaggers will be located at the closure area to direct traffic. Please plan ahead to find alternate routes.

The Portland Bureau of Transportation (PBOT) has approved a traffic control plan. In addition, PBOT and Environmental Services have installed traffic and pedestrian safety improvements along the detour route to make traveling safer and easier during this project.

The map on the right shows the recommended traffic detour route. We encourage people to plan ahead. You may want to find alternate routes or consider alternative work options such as teleconferencing or changing your schedule to avoid traffic, especially during rush hour.

If you use the recommended detour, please be aware of other travelers, especially people walking or biking. PBOT Traffic Control Engineers will be monitoring traffic in the area once the road closure begins and will make any necessary adjustments to the traffic control plan.

We appreciate your patience and understanding during construction as we work on this important project to restore connections for fish, wildlife, and people.

What to Expect During Construction

  • Local Access: Local access to all properties will be maintained, but construction activities may impact or delay normal use of your driveway. Please allow for extra time for our crews to make the area safe before entering or leaving the construction area.
  • Traffic Delays: You should also expect traffic delays in and near the work area. Please observe traffic control signs and follow the directions of flaggers if present.
  • Parking Restrictions: On-street parking will be restricted in and near the work zones to create a safe work environment and to stage equipment and materials.
  • Equipment Storage: Some equipment and materials may be stored overnight on your street, nearby streets, or other public right-of-way areas.
  • Noise, Vibration, and Dust: Construction creates noise, vibration, and dust.
  • Periods of Inactivity: Work will be conducted in multiple phases. A variety of factors, including conditions underground, weather, subcontractor schedules, and availability of materials may cause periods of inactivity.
  • Maintained Service: Water and other utilities will remain in service during construction.
