Even as Andrew Cuomo struggles to retain his governorship over mounting allegations of sexual harassment and bullying, his favorite construction boondoggle — the “Wrong-Way” LaGuardia AirTrain — got a shot in the arm Monday as the troubled project attained a key milestone. The Federal Aviation Administration yesterday published the final Environmental Impact Statement for the proposed $2-billion, 1.5-mile automated people mover, which was first proposed in 2015 and has hit multiple hurdles since — among them, the $3-billion hole that COVID-19 blew in the $20 billion capital plan of the project’s sponsor, the Port Authority of New York and New Jersey. The publication of the final EIS puts the final nail in the coffin of consideration of alternatives to the AirTrain plan — 47 were considered and rejected — and memorializes the public comments collected on the proposal. After the FAA issues a “Record of Decision” later this spring, AirTrain construction can move forward, “completing the transformation of LaGuardia Airport into a world-class gateway to New York,” per Port Authority literature. Initial utility work and foundations for the automated people mover guideway and stations will commence in June, the document says optimistically.
