The Walk Bike Clackamas Plan is a comprehensive, long-term vision to improve opportunities for people who walk and bike in Clackamas County.

Adopted Walk Bike Plan  Adoption Materials

The plan, which applies to all urban and rural unincorporated areas of Clackamas County:

• Establishes infrastructure priorities, such as where to build new bike lanes and sidewalks, which will help the county apply for future grants and other funding opportunities
• Identifies programs that increase safety and convenience of walking and biking (like Safe Routes to School).
• Updates active transportation polices and adopt performance measures so we can track progress during implementation
• Serves as the pedestrian and bicycle transportation elements of the county’s updated Transportation System Plan (TSP)

Key Terms and Definitions

• Active transportation: human-powered modes of travel, including walking, rolling a wheelchair, and riding a bicycle.
• Facilities and infrastructure: designated places for people to walk, roll, and ride a bike, such as off-street shared-use trails, painted bike lanes on streets, marked and signalized crosswalks, and sidewalks and multiuse paths.
• Equity: reducing or eliminating disparities by thoughtfully spreading resources to overcome the unique barriers different groups face.
• Health equity: providing fair access to opportunities and resources for people to achieve physical and social health and well-being, and reducing barriers caused by circumstances outside of a person’s control, such as race, ethnicity, or social background.
• Communities of interest: groups of people who have experienced or continue to experience inequitable access to resources in society. Walk Bike Clackamas is focused on achieving equitable outcomes for the following communities of interest:
  • Black people, Indigenous people, and People of Color (BIPOC)
  • Immigrants
  • People with limited English proficiency
  • Low-income and low-wealth community members
  • Low- and moderate-income renters and homeowners
  • People with disabilities
  • Youth and seniors

Timeline

The Molalla River (Knights Bridge Road) Bridge in the Canby area is an important connection for delivery of goods and services throughout the region. Bridge repairs will include painting, sealing cracks on the deck, resurfacing the deck, and repairing the concrete columns and bridge approaches. This project also includes seismic upgrades. 

Why

To preserve and extend the life of the bridge, to remove weight restrictions, allow for traffic to cross in an emergency, and to improve resiliency within our essential transportation network in the event of an earthquake.

Funding

• Project estimate $5.4 million
• Funding was provided from ODOT Local Bridge Program with a 10.3% match from county road funds 

Courtney Ave. is a narrow roadway with bike lanes and no sidewalks which creates potential conflicts between all users.

The complete streets project will improve safety and accessibility by providing 6-foot separated sidewalks on both sides of Courtney Avenue; 8-foot buffered bike lanes; intermittent rain gardens for stormwater management; street and pedestrian lighting and ADA compliant intersection curb ramps; and crosswalk enhancements at two intersections. The sidewalk and bikeway improvements will also provide a direct east-west connection to the Trolley Trail for travelers.

Why

To improve safety and accessibility for pedestrians and bicyclists with sidewalks and dedicated bike lanes, and an improved link to the Trolley Trail.

Project description

Although there are no immediate safety concerns related to the stability of the bridge or the roadway, the Bear Creek Bridge in the Molalla area is undersized. This project will replace the bridge and improve the roadside shoulders along S Molalla Ave from Sawtell Road to the Molalla City limits, just south of W 7th St. 

Why

To provide a safer bridge and roadway for all users. 

Schedule

• Design: Sept. 2024 - Dec. 2025
• Right of way: Fall 2024 - Fall 2025
• Construction: Spring 2026 - Fall 2026

• A full road closure and detour is expected for the bridge replacement project during construction.

Current activities

• No project activities are occurring at this time. 

Funding

• Project estimate $1.85 million. 
• Funding is provided from Community Road Funds and transportation system development charges. 

Welches Road is a main road without sidewalks or shoulders in the Welches area. To provide a safer roadway for all users, especially pedestrians, a project is planned between Hwy 26 and Birdie Lane. 

In 2016, the Welches community helped the county develop The Villages at Mt. Hood Pedestrian and Bikeway Implementation Plan. The plan prioritizes pedestrian and bicycle infrastructure improvements to create a connected system integrated with transit to meet the needs of residents and visitors, such as Safe Routes to School plans, enhanced Hwy 26 crossings, and identifying bicycle and pedestrian needs. The Welches Road project is identified as a high priority project within the Villages at Mt. Hood Pedestrian and Bikeway Implementation Plan.
 

Why

To provide a safer roadway for all users of the roadway, especially vehicles and bicyclists.

Paving the roadway and retrofitting curb ramps and traffic signals for ADA compliance  

Johnson Creek Blvd is a main road in the Milwaukie area with heavy volumes of vehicle traffic. The road will be repaved between 79th Pl and approximately 500 feet south of 45th Pl. Bell Avenue will also be repaved between Johnson Creek Blvd. and Alberta Ave. The median lane will be extended to Stanley Ave. to improve safety of left-turn movements onto Stanley Ave.

Sidewalk curb ramps and pedestrian push buttons will be checked for compliance with Americans with Disability (ADA) standards and retrofitted or replaced, as needed. 

Why

To provide a smooth traveling surface for motorists and bicyclists and to improve safety and accessibility for pedestrians.

Project description

The intersection of SE Amisigger Road and Hwy 224 (Clackamas Hwy) is an intersection with high volumes of traffic located east of Barton in a rural area, with a stop sign on SE Amisigger Road. Travelers attempting to turn east or west from SE Amisigger Road onto Hwy 224 during peak traffic periods can experience long wait times.  

As part of the project, we analyzed the intersection to determine whether to build a traffic signal or a roundabout. The evaluation determined a two-lane roundabout is less expensive and will be significantly safer. 

Why

To provide a safer environment for all travelers and reduce delays for vehicles on Amisigger Road turning onto Hwy 224.

Schedule

Design: May 2022 to Fall 2026
Right of way: Spring 2026 to Fall 2026 
Construction: Spring 2027 to Fall 2028

Traffic impact

Single lane closures may be needed during construction. Access to businesses and homes will be maintained during the construction.

Current activities

Design phase - 90%

The design team anticipates bidding the project in spring 2027 with construction starting in spring 2027 and lasting through 2028.

Funding

• Project estimate $5.4 million
• Funding is provided from Community Road Funds

Project description

The Duus Road and Eagle Creek Road intersection turn lanes lack adequate sight distance in the Estacada area. This project will construct a southbound left-turn lane on Eagle Creek Road and potentially a westbound left-turn lane on Duus Road.

The primary reason for crashes at this intersection is from failure to yield to oncoming traffic. To improve safety in this area, traffic signals will be installed at the intersection of SE 79th Place and SE Johnson Creek Blvd.

The project will also add sidewalks, and install ADA-compliant curb ramps at intersections and a raised median on Johnson Creek Blvd. from SE 79th Place to several hundred feet west to allow right-in and right-out only movements from both sides of the road.

Why

To provide a safer environment for all travelers by restricting turn options onto Johnson Creek Blvd and installing a signal for pedestrians to cross Johnson Creek Blvd.

Schedule

• Design: March 2023 to Feb. 2025
• Right of way: June 2023 to Feb. 2025
• Construction: Sept. 2025 to June 2026
   

Traffic impact

Construction starts Tuesday, Sept. 2. Expect single lane closures during construction between 7 a.m. and 5 p.m.

Current activities
