Roundabout to be installed on 172nd Avenue

This is a Clackamas County project.

For more information, contact project manager, Jonathan Hangartner at 971-804-2825 or jhangartner@clackamas.us.


A traffic roundabout is being installed at SE 172nd Avenue and newly developed SE Scouters Mountain Road. Roundabouts are often a safer alternative to more traditional traffic signals and stop signs as they provide increased travel efficiency. The project, which commenced in late summer, has primarily focused on such preparatory work as underground utility relocation and storm water system management.

The next phase of construction, which includes road widening and paving, will temporarily impact traffic to accommodate the physical creation of the feature. To complete this project, SE 172nd Ave. will need to be closed to through traffic in both directions from SE Troge Road to SE Hemrich Road. This closure is anticipated to begin Sept. 6 and continue through Nov. 1 (two full months). A detour will direct traffic to SE Foster Road to bypass the affected area. Once completed, the roundabout will help support future infrastructure development and allow for more ease of flow.
