Robert Moses nixed the GWB subway plan in favor of the cross bronx expressway. It would have been an extension of the IND 8th Ave line (A,C.E). The small 174th Street Yard where the connection would have been lies under Broadway, with two tracks exiting to the south under that roadway. The plan was to build over to Ft. Lee where there would have been a loop to include several area communities.
" When the George Washington Bridge was opened in 1931, the Port Authority had in place plans for four sets of tracks that would occupy a future lower level. By the time the ''Martha Washington'' level was planned in the 50's, the obsession was all with automobile tolls.
Austin Tobin, then the authority's executive director, made the final decision that discarded the two sets of tracks that were to tie in with the IND subway at 178th Street (the original terminus of that line in the planning stage) and two sets of rails to serve a future commuter line from Washington Heights into the Passaic-Bergen area.
That was the era of the Master Builder, Robert Moses, who built brilliantly but whose tunnel vision of road over rail has saddled our area with traffic congestion that appears almost insoluble."
