The intersection of SE 282nd Ave and SE Haley Road is an intersection with high volumes of traffic crashes located south of Hwy 26 in the Boring area. The project will study issues, and it will identify low cost improvements, such as enhanced signing, pavement markings, delineation, and improvements to the existing flashing beacon.

Why

To provide a safer roadway for all users and reduce traffic crashes at the intersection.

Funding

• Project estimate $35,249.
• Funding is provided from the Community Road Fund.

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.

  All right of way acquisitions are conducted as required by state and federal law. Read right of way brochure: English | Spanish.
• Construction: summer 2026 – winter 2026/2027 

Traffic impact

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

Current activities

• Project design phase.

Funding

• Project estimate $6.6 million 
• Funding is provided from the county road funds, transportation system development charges and capital federal funds through a Metro 2022–24 Regional Flexible Fund Allocation Grant and ODOT.

Sunnyside Road is a main road with high traffic volume located east of I-205 in the Happy Valley area. The project installed ADA compliant curb ramps at each intersection along Sunnyside Road between 122nd Ave. to 162nd Ave. The project also improved traffic signal push button access for pedestrians.

In summer 2022, this portion of Sunnyside Road will be repaved.

Why

To provide a safer roadway for all users especially people with disabilities and pedestrians.

Funding

• Project estimate $2.8 million.
• Funded by the county road fund.

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

Traffic impact

• 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. 

The intersection of Beavercreek Road and Henrici Road is an intersection with high volumes of traffic located southeast of the Oregon City area. The project installed a special radar detection system to detect vehicles as they approach the intersection. The detection prevents the signal from changing to another direction prematurely and placing drivers in a dilemma of deciding to go through the intersection or not, causing longer wait times. The project also added reflective material to traffic signal heads to increase visibility.

Project description

Why

To provide a safer roadway for all users and reduce wait times at the intersection.

Funding

• Project cost $50,690
• Project funded by the Community Road Fund.

Final Report, October 2022 

Traffic levels in Canby have significantly increased as population has grown in the Canby area and the greater region, including the travel time between Canby and  I-5. The county and the City of Canby studied options to reduce travel times between I-5 and Canby.

This project studied possible improvements at the intersections of Barlow Road and Arndt Road, and also Barlow Road and OR 99E. The county determined if an exception to statewide planning goals will be necessary due to farmland impacts. For each option, this project:

• Estimated benefits, costs, and traffic impacts in the area
• Identified critical traffic issues
• Analyzed how the possible tolling of I-205 would change traffic demands in the Canby to I-5 area
• Identified any farmland impacts that would require a statewide planning goal exception
• Determined which options merit further study

Why

• To improve the connection between the west central portion of Clackamas County, including Canby and Mulino, with I-5.
• Improve the attractiveness of Canby as a business location by reducing the travel time and length between Canby and I-5 to improve the attractiveness of Canby as a business location and reduce greenhouse gas generation.
• Improve the traffic flow and reduce wait times during peak traffic periods at the intersections of OR 99E/Barlow Road and Arndt Road/Barlow Road.

Schedule

• The county began the study in spring 2021 and completed it in fall 2022.

Funding

• Project cost:  $188,173
• Funding provided from the Community Road Fund

The intersection of Johnson Creek Blvd. and Bell Ave. is an intersection with high volumes of traffic located in the Milwaukie area. The project will enhance the existing traffic signal by installing a special radar detection system to reduce wait times and minimize travelers running red lights, add reflective material to traffic signal heads to increase visibility, and add signal ahead warning signs.

Why

To provide a safer roadway for all users and reduce wait times at the intersection.

Funding

• Project estimate $6,466.
• Funding is provided from the Community Road Fund.

The intersection of Bob Shumacher and Causey Road is an intersection with high volumes of traffic located east of I-205 in the Happy Valley area. The project will install a flashing yellow arrow signal and a special radar detection system to improve vehicle and pedestrian safety and reduce wait times, add reflective material to traffic signal heads to increase visibility and add signal ahead warning signs.

Why

To provide a safer roadway for all users and reduce wait times at the intersection.

Funding

• Project estimate $89,933.
• Funding is provided from the Community Road Fund.

The intersection of Johnson Creek Blvd. and Bell Ave. is an intersection with high volumes of traffic located in the Milwaukie and Happy Valley areas. The project will enhance the existing traffic signal by upgrading to newer vehicle detection (radar sensors) system to improve signal timing, upgrading all existing 8” signal heads to 12” standard size signal heads, replace older style left-turn signal heads with current standard flashing left-turn arrows with “pedestrian friendly” signal timing, add reflective material to traffic signal heads to increase visibility, and add signal ahead warning signs.

Why

To provide a safer roadway for all users and reduce wait times at the intersection.

Funding

• Project estimate $6,679.
• Funding is provided from the Community Road Fund and 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.
