The extension of the NYC Transit #1 subway line from the Rector Street station to Red Hook for $3.5 billion (a tunnel and three new stations) as proposed in 2016 by Senior VP of AECOM Engineering firm Chris Ward and now supported by Governor Andrew Cuomo in his 2018 State of the State speech is wishful thinking.
This subway extension would support a proposed Red Hook economic development project. It would be similar in size and scope to Battery City Park in Manhattan. Was this $3.5 billion figure written on the back of a napkin?
Cuomo wants the MTA to conduct and pay for a planning feasibility study. There would still be the need for environmental documents or preliminary design and engineering followed by final design and engineering efforts and identification of billions for construction funding.
All of the above is necessary to validate any basic estimates for construction costs.
Given the narrow streets and dense development, who could find a staging area for mobilization of contractor employees, equipment and materials to support construction? Imagine trying to assemble a tunnel boring machine at Rector Street adjacent to the Brooklyn Battery Tunnel. What about removal of debris once excavation begins? Hundreds of trucks needed on a daily basis to remove rock and soil would be challenging.
It cost $4.5 billion for Phase 1 Second Avenue subway (36 blocks & 3 stations) & $2.4 billion (18 blocks & 1 station) for #7 Hudson Yards subway extension. Neither required a multi-billion tunnel under the East River. Construction of new subway stations average between $500 million up to $1 billion, depending upon location and complexity of work. All three new subway stations would require compliance with the Americans with Disability Act (ADA). This includes expensive elevators and other features.
Is there a political quid pro quo in the form of campaign donations between developers, construction contractors and unions who support this project and Cuomo?
