Transportation Engineering

Heavy rains caused a portion of 232nd Dr. to sink and created large cracks in the pavement in the Barton area. The project will install a deep patch of pavement and improve drainage capacity.

Why

To ensure reliable connection to OR 224 and OR 212 and reduce ongoing maintenance costs.

Funding

• Project estimate $760,000.
• Funding is provided from Federal Highway Administration grant funds, County Road Funds and HB2017 state gas tax funding.

The intersection of King Road and SE 66th Ave. is an intersection with high volumes of traffic crashes located in the Milwaukie area. Traffic engineers studied the intersection and determined needs such as adding flashing lights at the crosswalk on the east side of the intersection, upgrading curb ramps to meet Americans with Disabilities Act standards and upgrading lighting. This project will be included in the Walk Bike Clackamas Plan and in the Transportation System Plan.  

Why

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

Schedule

The county completed traffic safety analysis in Dec 2022. The analysis recommends constructing an enhanced crosswalk as funds become available.

Current activities

Analysis complete

The project will install a guardrail along 400 feet of Dryland Road between Heinz Road and Barnards Road at the curve.

Why

Dryland Road is a rural road with a slight curve immediately south of a crest in the Molalla area. To prevent future vehicles from leaving the roadway, and to reduce the severity of future lane-departure crashes along this segment of Dryland Road.

Schedule

• Design: July 2019 - June 2020
• Right of way: April 2020 - July 2020
• Construction: May 2023 - Sept. 2023 

Traffic impacts

Expect single-lane closures during construction starting in mid-May.

Current activities

Preparing for construction. 

Funding

• Project estimate $465,000.
• Funding is provided from County Road Funds.

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.

60% design map

Why

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

Schedule

• Project planning and design: Sept. 2023 – winter 2025/2026
• Right of Way Acquisition Efforts: March 2025 – spring 2026 
  All right of way acquisitions are conducted as required by state and federal law. Read right of way brochure: English | Spanish.
• Construction: summer 2027 – 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. 

Map of Curb Ramp Installations

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 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.
