The Foundry Branch Trolley Trestle is one of only two remaining bridges along the former trolley line linking Georgetown and Glen Echo, Maryland. This line, constructed around 1900, provided the transportation to a ‘trolley’ park and thousands of Washingtonians used the line annually to access the Glen Echo Amusement Park. Although all the tracks have been removed, the right-of-way continues as a trail along the Potomac River overlook through the Palisades neighborhood of Northwest Washington, DC. The steel bridge span crossing Foundry Branch in Glover Archbold Park is an excellent example of one of the few remaining early transportation bridges in the city. Weathering and a lack of maintenance have seriously damaged the structure, and the trestle now stands with the help of improvised cables.

As of April 2018, WMATA, the owner of the Trestle has filed an application to demolish the Trestle. The hearing is scheduled before the Historic Preservation Review Board on May 24th.  Click here to read the staff report.
