The East Broadway station opened on January 1, 1936, as the southern terminus of the first four stations to open on the Sixth Avenue Line. Two local tracks split from a junction with the Eighth Avenue Line south of West Fourth Street–Washington Square, running east under Houston Street and south under Essex Street to a temporary terminal at East Broadway. The station was initially served by E trains to Church Avenue. Just after midnight on April 9, 1936, trains began running under the East River via the Rutgers Street Tunnel, which connected the Houston-Essex Street Line with the north end of the Culver Line at a junction with the Eighth Avenue Line north of Jay Street–Borough Hall. E trains were sent through the connection to Church Avenue. When further sections of the Sixth Avenue Line opened on December 15, 1940, the F train replaced the E train at the East Broadway station.
