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—continues 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.
Above image is the schematic design of the new bridge and culvert.
Our contractor, MJ Hughes Construction, continues construction on SW Boones Ferry Road, between SW Arnold Street and SW Comus Court. Construction and the road closure will last up to seven months.
Between Friday, May 22 and Friday, June 12, our contractor continues the process of installing piles (metal casings) into the soil. These piles are the foundation of the new bridge.
Because our contractor was able to successfully complete the majority of pile installation with the vibrating equipment, driving the piles deeper into the soil with a pile hammer is only expected to take a couple days. However, due to a mechanical issue, driving piles has been delayed until Tuesday, May 26.
After pile installation is complete, roadway excavation will begin. This process will take a month or more to complete.
The schedule may change due to a variety of factors, including weather, conditions underground, availability of materials and labor, and other factors. Work hours are from 7 a.m. to 6 p.m., Monday through Friday, and Saturdays as needed.
A driven pile is a long, slender column made of preformed material that can be installed by impact hammering, vibrating, or pushing it into the ground to a specific depth. Driven piles are a form of building foundation that provide support for structures, transferring their load to layers rock and soil underground that can carry the weight of the structure above.
Environmental Services recognizes that people staying at home due to COVID-19 will have significant disruption since driving piles with a pile hammer can be very loud, and the sound of the hammer striking a pile will be heard outside of the construction zone. However, this method of construction ensures the foundation of the new bridge will be stable and safe for decades to come.
We apologize for the inconvenience and appreciate your cooperation and patience as we continue to construct the new bridge.
Safety is our priority, and we want to ensure a safe construction site for our construction team as well as the community.
Do not enter the project site. All trails are closed through the construction area. Do not bike, hike, or play in the restricted area.
Please remind your children that this area is off-limits at all times and days.
All trails leading to the construction site are closed. Park Rangers will be patrolling the area and conducting enforcement actions to ensure that people stay out of the construction site. If you are caught trespassing on the project site, you will be subject to a fine.
If you see trespassing on the project site during non-construction hours, please contact the non-emergency line for the Portland Police at 503-823-3333.
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.
