Clackamas River (Trolley Trail) Preliminary Design
Status
Design phase
Updated: Jan. 18, 2024
The need remains for a transportation link for people that walk and bike across the Clackamas River to connect the cities of Gladstone and Oregon City.
This phase of the project will identify a preferred bridge structure type and perform up to 30 percent engineering design. The bridge will replace the recently demolished Portland Ave Historic Trolley Bridge and connect the existing Trolley Trail, a shared-use path for bicyclists and pedestrians, to trails that exist along the Clackamas River on the Oregon City side of the river.
The bridge design continues the work completed in a previous feasibility study. Clackamas County is assisting the City of Gladstone through the design process using the county's ODOT certification.
Why
To improve active transportation access across the Clackamas River for pedestrians and bicyclists in the Gladstone and Oregon City areas.
Schedule
Design: March 2024 – Dec. 2025
Traffic impact
No traffic interruptions during design phase.
Current activities
Project design
Funding
- Project estimate $1.37 million
- Funding is provided from federal funds through the Metro 2022-24 Regional Flexible Fund Allocation Grant and from the City of Gladstone.
Bridge structure options
#1 Single-Span Steel Truss
#2 Three-Span Precast Concrete Girder
#3 Three-Span Steel Girder

Bluff Road/327th Ave. Intersection Enhancements
Status
Planning phase
Updated: Sept. 17, 2024
The intersection at 327th Ave and Bluff Road is located on a sharp curve with a skewed intersection angle in the Boring area.
To improve the safety of the intersection, we will reconfigure the approaching roads and the intersection, add a westbound left-turn lane, improve drainage, remove a portion of pavement, and add signs and pavement markings. We will also consider street lighting enhancements.
Why
To improve sight distance and reduce the frequency and severity of traffic crashes.
Schedule
- Design: June 2024 through June 2025
- Construction: Summer 2026
Traffic impact
Intermittent lane closures may occur during construction
Current activities
Project planning
Funding
- Project estimate $114,000.
- Funding is provided from the Community Road Fund.
Projects funded through the new Community Road Fund will increase safety, relieve congestion and maintain local roads.

Canby Ferry Ramp Improvements
Protecting the Canby Ferry and improving operations
Status
Design phase
Updated: Dec. 13, 2023
The north ramp landing for Canby Ferry traffic moves during significant water level changes on the Willamette River and disrupts ferry operations and can damage the bottom of the boat. The north ramp will be replaced and the south ramp stability will be evaluated.
Why
To protect the ferry structure and improve operations.
Schedule
- Design: fall 2024 to fall 2026
- Construction: summer 2027 to fall 2027
Traffic impacts
Expect delays or closures to ferry operations during construction.
Current activities
Project planning and solicitation of design services.
Funding
- Project estimate $550,000.
- Funding is provided from federal Ferry Boat Discretionary Program funds and county road funds.

Laurie Ave Stormwater Improvements
Status
Coordinating construction
Updated: Feb. 24, 2025
Extending Stormwater Infrastructure to Laurie Ave.
The project will install a new 12-inch diameter stormwater main on 436 feet of Laurie Avenue south of Courtney Ave and 6 catch basins to reduce the frequency of flooding. Additionally, 300 feet of stormwater main on Courtney Avenue west of Laurie Avenue will be replaced with 12-inch diameter stormwater pipe.
Why
The new stormwater main and catch basins are expected to reduce flooding and convey a 10-year storm event.
Schedule
- Design: June 2023 to April 2024
- Construction: March 2025 to July 2025
Traffic impact
Construction is planned to start Monday, March 10, 2025. Expect delays on Laurie Ave and Courtney Ave between 7 a.m. and 6 p.m.
Current activities
Surveying and design services.
Funding
- Project estimate $800,000.
- Funding is from county road funds.

Abernethy Creek (Holly Ln) Bridge Replacement
Status
Planning phase.
Updated: March 21, 2023
Ensuring all traffic can cross the bridge without weight restrictions.
The Abernethy Creek (Holly Lane) Bridge crosses Abernethy Creek in the Oregon City area. The bridge has weight restrictions for traffic due to deficiencies in the concrete deck, floor beam cracks, and weakness of the gusset plates and will be replaced to current design standards.
Why
To carry travelers without load restrictions for all traffic including emergency response and commercial truck traffic.
Schedule
- Design: Winter 2025 to Spring 2027
- Right of way: Winter 2026 to Spring 2027
- Construction: Spring 2027 to Winter 2028
Traffic impact
Expect delays or closures during construction.
Current activities
Waiting for funding agreement to initiate bid proposal for engineering design.
