Traffic Advisory: SW Boones Ferry Road lane closures start Feb. 24 for Tryon Creek bridge and restoration project; full road closure starts March 30

(February 20, 2020) – The City of Portland Bureau of Environmental Services advises the traveling public to expect intermittent lane closures on SW Boones Ferry Road near SW Arnold Street beginning Feb. 24 and continuing through March. SW Boones Ferry Road will be completely closed in both directions beginning March 30 for up to seven months.

The closures will allow Environmental Services contract crews to build a new bridge on SW Boones Ferry Road where it crosses Tryon Creek to create better connections for fish, people and wildlife. The new bridge will allow the creek to flow freely, replacing an aging culvert that blocks healthy water flow and native fish. Crews  also will build a pedestrian and wildlife trail under the bridge that connects to the area’s existing popular trail network.

Lane closures will occur intermittently through March 30 while workers prepare the construction site. One lane will remain open at all times. Lane closures may occur any time during work hours, which are from 7 a.m. to 6 p.m., Monday through Friday, and Saturdays as needed.

The public is advised to travel cautiously, expect some delays, observe directions of reader boards and flaggers, and use alternate routes when possible.

For the full closure, a recommended detour directs SW Boones Ferry Road travelers to use SW Stephenson Street and SW 35th to reach SW Terwilliger Boulevard. The full closure will be in effect all hours, all days, to all travelers, including non-motorized use.
