The northbound platform formerly had an additional entrance at Hayward Place, with separate entrance and exit headhouses on the north side of Hayward Place; the concourse and headhouses are extant (and used as emergency exits) but are embedded into a newer building. A disused northbound entrance is located on the south side of Essex Street east of Washington Street. A disused entrance to the southbound platform was located at Lagrange Street; it also serves as an emergency exit. A disused sub-passage connects the inbound and outbound platforms.
