Clackamas River (Trolley Trail) Pedestrian Bridge

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.
