172nd / 190th Corridor Plan



Clackamas County Clackamas County, in coordination with Damascus, Gresham and Happy Valley, conducted a planning project to identify the future look and alignment of 172nd Avenue north of Sunnyside and to determine how it will connect to 190th Drive in the Gresham area.

This project is needed to accommodate the future traffic demand that will come with the buildout of developable land in Happy Valley, Damascus, and Gresham, and there is a need for a north-south connection to accommodate local and regional traffic growth. There are limited locations where this type of connection/facility can occur due to topographic constraints and existing urban buildout. View maps of the study area in Study Area Resources.

To learn more about why this project is needed and why it is being conducted at this point in time, watch the video below:

The 172nd/190th corridor plan project was completed in February 2012.
