The Cedar Street subway is a rail tunnel in Newark that allowed street cars (and later buses) access to the subterranean level of the Newark Public Service Terminal.
It was built by the Public Service Corporation in 1916, as part of the terminal building, to reduce streetcar congestion at nearby Broad and Market streets, and provided access for a number of surface lines.
Later, across the tracks, an outbound platform was added serving McCrory's 5 & 10 store.
In 1935, the Cedar Street subway was extended to a junction with the newly opened Newark City Subway, allowing service to extend to Newark Penn Station.
Since the demolition of the Public Service Terminal in 1981, it has ended at a wall under Broad Street.
