Clackamas Regional Mobility Logo


To construct a package of multimodal projects to meet transportation needs in the Clackamas Regional Center through the year 2040. Traffic congestion in this area presented major challenges affecting safety, multimodal access, and economic development. The completed project:

  • Provides a safe and efficient transportation system
  • Addresses needs of residents, businesses, and the public
  • Balances different modes of transportation: motor vehicle, bicycle, pedestrian, transit, and freight


Major components of the project are complete. The public can expect to see minor work occurring in early 2022, but only minor traffic disruptions are anticipated.

Improvements include

  • Harmony Road between 80th Avenue and Fuller Road, including the pedestrian crossing at Clackamas Community College.
  • Sunnyside Road between SE 82nd Avenue and SE Stevens Road, including improvements to the I-205 Overcrossing and Interchange.
  • SE 80th Avenue between Harmony Road and Southgate Street.
  • SE 93rd Avenue and SE 97th Avenue Intersections with Sunnybrook Boulevard.
  • SE 82nd Avenue, including upgrades at Sunnyside Road and Sunnybrook Road

Improved travel options

Local residents benefit from new and improved opportunities to walk, bike, and take transit with better connections to the Town Center Max station and I-205 bike path. New lighting and landscaping enhance safety and aesthetics, especially along SE Sunnyside Road between the Clackamas Town Center and Clackamas Promenade.

Employees and employers at Kaiser Sunnyside Medical Center, Sunnyside 205, One Town Center, Clackamas Town Center, Clackamas promenade, and business along SE 82nd Avenue in the project area have improved access to work whether driving, walking, biking or taking transit.

Transportation improvements that link transit, walking and biking in the area serve youth and students at Clackamas Community College Harmony Campus, Clackamas Middle College and La Salle Catholic College Preparatory, and visitors to the North Clackamas Aquatic Park.

Shoppers benefit from removal of the slop lane into the Clackamas Town Center to alleviate congestion in the parking lot. Restriped travel lanes, modified traffic signal timing, and new signage will help shoppers get to and from their destinations smoothly and safely.

Improved traffic operations at several intersections help commuters and freight traffic traveling to and through the Clackamas Regional Center, including SE Sunnyside Road at 82nd Avenue, SE Sunnyside Road at SE Stevens Road, and I-205 on-and off ramps.
