SE 172nd Ave. Widening and Infrastructure Improvements

Status

Project is in design phase.

Updated: Jan. 19, 2023

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

Improvements at major intersections include adding a traffic signal at Troge Road and Crossroads Ave, a multi-lane roundabout at Hemrich Road, a multi-lane roundabout at the future 190th Ave intersection, and expanding the single-lane roundabout at Scouters Mountain Road to a multi-lane roundabout. Includes 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.
