The current Archer Avenue plans emerged in the 1960s under the city and Metropolitan Transportation Authority (MTA)'s Program for Action. It was conceived as an expansion of Queens Boulevard service to a Southeast Queens Line along the right-of-way of the Long Island Rail Road (LIRR) Atlantic Branch towards Locust Manor, and as a replacement for the dilapidated eastern portions of the Jamaica Avenue elevated within the Jamaica business district which business owners and residents sought removal of; both would meet at the double-decked line under Archer Avenue. The two-track spur from the Queens Boulevard Line would use the original Van Wyck Boulevard bellmouths. Design work on the line began in 1969. The lines and the Jamaica El removal were part of urban renewal efforts in the Downtown Jamaica area. This included the construction of the York College campus, which was planned to be built in conjunction with the LIRR Atlantic Branch connection. The connection to the Jamaica Line, Route 133, was to begin at Jamaica Avenue and 127th Street and continue as an elevated to the LIRR embankment and then go underground at 91st Avenue before connecting with the Archer Avenue line at 132nd Street. Route 133 was to be over long.
