The purpose of the Clackamas Regional Mobility Improvement project is 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 presents major challenges affecting safety, multimodal access, and economic development; therefore, the Project aims to:

  • Provide a safe and efficient transportation system
  • Address needs of residents, businesses, and the public
  • Balance different modes of transportation: motor vehicle, bicycle, pedestrian, transit, and freight


In consultation with the public and technical advisors, the County identified projects that will benefit residents, businesses, and the traveling public. How will you benefit? 

Local residents will 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 will 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 will have improved access to work whether driving, walking, biking or taking transit.

Transportation improvements that link transit, walking and biking in the area will 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 will 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 will help commuters and freight traffic traveling to and through the Clackamas Regional Center. Major intersections to be improved include SE Sunnyside Road at 82nd Avenue, SE Sunnyside Road at SE Stevens Road, and I-205 on-and off ramps.


In 2017, the Board of Commissioners approved the Clackamas Regional Center Mobility Improvements Project that identified over 30 transportation projects to improve safety and increase traffic flow for motorists, bicyclist, pedestrians, and transit riders. This approval was based on extensive input from the public and technical representatives who advised the County and its design team, Harper Houf Peterson Righellis Inc., on project selection and prioritization.

Public Input. A Stakeholder Task Force advised the design team on community values and criteria to be used in evaluation of the package of transportation improvements. This task force included local residents, representatives from the area businesses and schools, CPO Representatives and environmental interests. Other outreach to solicit public input included an open house, a website with virtual open house and presentations to the Clackamas CPO and North Clackamas Chamber of Commerce. The design team also held one-on-one meetings with representatives from the Clackamas Town Center, Clackamas Promenade, Kaiser Permanente, and Clackamas Community College – Harmony Campus. The Stakeholder Task Force unanimously recommended a package of improvements in November of 2016.

Technical Input. A technical Task Force consisting of representatives from Clackamas County transportation planning, engineering, and maintenance departments; the cities of Milwaukie and Happy Valley; and TriMet and ODOT met twice. Additional working meetings were held with TriMet, ODOT, and the County Pedestrian and Bike Advisory Committee to address specific issues or subareas.

Following approval by the Board of County Commissioners, the County’s consultant design team, Harper Houf Peterson Righellis Inc., designed the project, leading to construction of the first set of improvements slated to start in January 2020. Funding is from tax increment revenue raised by the Clackamas Town Center Urban Renewal District Project.
