SE 172nd Ave. Widening and Infrastructure Improvements | Clackamas County

Design

Updated: Dec. 4, 2024

Happy Valley has been developing at a rapid pace. Developing the infrastructure along 172nd Ave is a high priority for the city and county. 172nd Ave will be widened to four travel lanes with a center planter median and turn lanes between Misty Dr to Scouters Mountain Road with added bike lanes, landscape strips and sidewalks.

Improvements at major intersections will include adding a roundabout at Troge Road and expanding the single-lane roundabout at Scouters Mountain Road to a multi-lane roundabout. Improvements will also include right of way acquisitions, moving existing utilities underground, replacing culverts at Troge Road, enhancing pedestrian crossings and adding street lighting.

The City of Happy Valley will be assisting in project coordination and review. The county will manage and lead the design and construction activities.

To reduce congestion, improve safety, provide safe routes and connectivity for bicyclists and pedestrians and to keep pace with future growth of Happy Valley.

Learn more about the project and ask questions or share concerns in-person at the open house between 5:30 and 7:30 p.m., Tuesday, February 20 in the community room at Happy Valley City Hall.
