Street View 




After more than five decades, unused and neglected, the Districtís last remaining streetcar trestle is crumbling. Sections of the steel supports have rusted away. Wooden ties have fallen. And its structural condition is so poor that the National Park Service closed a trail directly underneath it last August.

Still, preservationists say the state of the 122-year-old bridge, visible from Canal Road in Georgetown, isnít terminal. A plan to turn it into a pedestrian walkway could breathe new life into it, taking it off the list of the most endangered places in the District and putting it back in service, decades after the trolley line from Georgetown to Glen Echo ceased.

Located north of the Potomac River in Glover-Archbold Park, east of Foxhall Road NW and west of the Georgetown University campus, the trestle was once a critical passage point for the trolley line that transported thousands of people from Georgetown to the amusement park at Glen Echo in Maryland.

The trolley required numerous trestles to carry the tracks over water, along the Potomac. It is the last one standing in the District, officials with the historic preservation office said.

Unless a miracle happens, this bridge is a goner: https://wtop.com/dc/2020/01/ddot-decides-not-to-help-save-th...

This old trolley trestle is planning for repairs of the former Glen Echo Streetcar line. Very old abandoned trolley tracks can cause the trolley trestle to collapse. For a rare reason, if you're not sure about this, a very old bicycle is stuck when the trolley stopped its operation.
