In this video, we will talk about the Nostrand Ave extension. […] There is one plan that was not mentioned in this video, but we still wanted to talk about. This plan involved a different IND South 4th St Line, where it would be rerouted via Bedford Ave and join with the IRT Nostrand Ave. Since the IRT Nostrand Ave Line was built under Dual Contracts No. 3 and 4, it meant all lines under the plan had provisions to be widened just in case the IND wanted to take them over (because IRT tunnels are narrower than BMT and IND tunnels). The only remnant for this is when the IND suddenly decided to make Nostrand Ave an express station during construction, and not to make Franklin Ave an express station, even though Franklin Ave already had a connecting line (today's Franklin Ave shuttle).
