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.

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.

County Roads Take Me Home stickerProjects 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.
