Transportation Engineering

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.

Schedule

Design: Nov 2024 - Fall 2025

Right of way: Spring 2025 - Fall 2026

Construction: Spring 2027 to Fall 2027

Traffic impact

No impacts to traffic at this time. Single lane closures and detours may be needed during construction.

Current activities

The design team is ready to narrow down costs and considerations for the path including tree impacts and lighting, and interested in any construction concerns you may have. Share your feedback and preferences in the survey through Friday, September 5, 2025 at https://metroquestsurvey.com/gu7w7u?c=w.

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.

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 2025
Right of way: March 2025 to Fall 2025 
Construction: Spring 2026 to Winter 2027

Traffic impact

Limited impacts this year with survey work and traffic data collection. Single lane closures may be needed during construction. Access to businesses and homes will be maintained during the construction.

Current activities

Design phase - 60%

We expect to receive final approval from ODOT by the end of February and to start the Right of Way phase in March. The design team anticipates bidding the project in spring 2026 with construction starting in early summer 2026 and lasting through 2027.

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. 

Why

To improve safety and sight distance, relieve congestion and to accommodate future growth in the Estacada area.

Schedule

Design: July 2022 to Fall 2024 
Right of way: Winter 2024 to Fall 2024 
Construction: Spring 2026 to Fall 2026

Traffic impact

Expect lane closures and detours during construction.

Current activities

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

Pre-construction coordination.

Funding

• Project estimate $2.5 million
• Funding is provided from All Roads Transportation Safety (ARTS) Grant, Clackamas County Development Agency Funds, Condition of Approval Permit Funds, County Road Funds, and Community Road Funds

The intersection of Canby-Marquam Hwy and Lone Elder Road is a T-intersection that is stop-controlled on Lone Elder Road and uncontrolled along Canby-Marquam Hwy. The project reconstructed the intersection and added a northbound left-turn lane. Congestion in the northbound direction on Canby-Marquam Hwy occurs in large part from vehicles waiting to turn left onto Lone Elder Road.

Why

To reduce wait times on Canby-Marquam Highway at Lone Elder Road and create a safer intersection for all travelers.

Schedule

• Design: March 2020 - Dec. 2021
• Right of way: Nov 2021 - Oct. 2022
• Construction: Aug. 2023 - Oct. 2023

Funding

• Project cost $1.05 million funded by the Community Road Fund and countywide transportation system development charges.

The Rhododendron Main Street redevelopment plan provided an opportunity for the county, residents and businesses to meet the needs of reducing demand on the transportation system while accommodating desired housing near along Hwy 26. The project area is almost 4 acres centered on two privately held properties on the southwest side of Hwy 26. Publicly owned lands next to the project include the Rhododendron Swinging Bridge and Rhododendron Community Landscape at the Barlow Trail Oregon Historic Marker.
