SW Boones Ferry Bridge and Restoration Project

Updated February 20, 2020

Note:  SW Boones Ferry Road will be closing on March 30, 2020.  Please click here for more information.

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

Previously, we specified March 19 as the full road closure date. Due to a delay in the pre-construction phase, the full road closure and major construction activities will occur on March 30, 2020.

This project will be completed in late 2020 or early 2021. The schedule may change due to a variety of factors, including weather, conditions underground, availability of materials and labor, and other unforeseen events. In general, work hours will be from 7 a.m. to 6 p.m., Monday through Friday, and Saturdays as needed.

What Is Happening Now?

Prior to full road closure, work crews continue to conduct ongoing pre-construction activities including marking underground utilities with temporary paint, surveying the land, tree trimming, installing tree protection, installing erosion control measures, staging equipment and materials, setting up traffic controls, and relocating utility and communication lines.

In order to protect the public from pre-construction activities and safely separate construction crews from oncoming vehicles, SW Boones Ferry Road where it crosses Tryon Creek may need to be narrowed to a single lane near the project site. The single-lane closure is intermittent and dependent on the type of pre-construction activity. SW Boones Ferry Road will remain open, but you may experience delays in and near the work area.

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.
