After the project was shut down, the tunnel entrance was sealed. The station, built in part of the basement of the Rogers Peet Building, was reclaimed for other uses until the entire building was lost to fire in 1898. In 1912, workers excavating for the BMT Broadway Line (serving the present-day ) dug into the old Beach tunnel, where they found the remains of the car, the tunnelling shield used during initial construction, and even the piano in the subway's waiting room. The shield was removed and donated to Cornell University, which has since lost track of its whereabouts. The tunnel was almost completely within the limits of the Broadway Line's City Hall station, but it is rumored that a small portion could still be accessed by a manhole on Reade Street. The New-York Historical Society commissioned a plaque honoring Alfred Beach to be placed in the City Hall station.
