SW Boones Ferry Bridge and Restoration Project

Sign up for email construction updates

Updated August 5, 2020

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.

To view construction photos, visit our flickr album here: The SW Boones Ferry Bridge & Restoration flickr album will be periodically updated with milestone pictures.

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.

Fish Salvage At Tryon Creek

As crews continue construction on the bridge and culvert, Environmental Services fish biologists coordinated with the contractor to capture and relocate fish from the project area to a safer area downstream. During this process, they were able to safely relocate a wide range of species, including Coastal Cutthroat Trout and Reticulate Sculpin.

Check out the project flickr page to see some of the fish that were saved.

Look-ahead Schedule

Between August 5 and August 28, our contractor is prepping to pour the concrete bridge deck. Crews will install a special bridge paving machine to complete this important project milestone. Pouring concrete is scheduled to occur on August 14, beginning at 5 a.m. (see information on the proposed early start time below).

Below the bridge, crews have begun installing streambed stabilization measures and will install water control measures for the stream enhancement.

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.

Proposed Early Construction Start Time

Environmental Services will be pouring concrete for the bridge deck on August 14. Concrete work can only be done during dry weather, and there is significant amount of concrete that needs to be poured.

Because of this, crews will need to begin work at 5 a.m. on August 14. This early morning start time will allow our crews to take advantage of the cooler weather and give more time to ensure that the concrete cures completely. Equipment that will be used during the pour does generate noise and could include pumps and generators.

Submit Comments On The Noise Work

Work after 6 p.m. and before 7 a.m. and all hours on Sundays requires a noise variance from the Portland Noise Office. Environmental Services will apply for a noise variance to enable the city’s contractors to begin work at 5 a.m. on August 14 at this location.

Your comments regarding the proposed schedule to begin work at 5 a.m. on August 14 are valuable and can be submitted by email or phone to:

Portland Noise Office


Phone: 503-823-7350

Please submit your comments by Tuesday, August 11.
