This is the 1913 Map showing how the  rapid transit lines will look after completion in accordance with the Dual Contracts. Note two unfinished BMT lines that were proposed in the contracts but never finalized: The BMT Crosstown Elevated, which was later built as today’s “G” line Subway (although not exactly along the same route). Also note that the Flushing line was not supposed to terminate at Main Street but was supposed to continue to the East.
