former Riverside train station (East Providence, RI)
This railroad line, which was abandoned in the 1930s and converted to the East Bay Bicycle Path in the early 1990s, was originally built in 1855 by the Providence, Warren & Bristol Railroad. During the 19th century the line was operated first by the Boston & Providence RR and then the Old Colony RR, before being acquired by the New York, New Haven & Hartford RR in 1893. Trains reached this line from Providence by traveling over the now-abandoned Seekonk River Railroad Bridge.
I'm not sure of the exact history of this station. The building is currently for sale, and one real estate website listed its year of construction as 1850, making it possibly original to the line, and built by the PW&B.
The current (or most recent) occupant of the building is a tanning salon.
