Trolley Trail Bridge Feasibility Study

Project description: Clackamas County is assisting the City of Gladstone, who received federal grant funding from the Regional Flexible Funds Allocation (RFFA), in studying the feasibility and location of constructing a bridge in the abandoned Trolley Trail Bridge crossing of the Clackamas River.

Studying the feasibility of replacing the Trolley Trail Bridge for pedestrians and bicyclists would provide a much-needed active transportation link across the Clackamas River linking the City of Gladstone and Oregon City, and become a signature landmark for the popular Trolley Trail.
