The B&O crossed Connecticut Ave at grade for nearly 97 years. The Purple Line project recently installed the new bridge across the roadway, which sits atop the original B&O crossing. Avid fans will recall that Connecticut Ave. was the original terminus for what would become the Georgetown Branch, as the railroad served the Rock Creek Ry. power plant and a growing industrial area including T.W. Perry and other merchants.
Here is a photo of unknown origin showing the crossing ca the late 1800s:
I previously posted a time lapse video of this bridge’s installation.
