The original estimated cost for the proposed light rail project between Jamaica and Long Island City on the old Lower Montauk LIRR branch was $100 million. The just released feasibility study for this project forecast a potential cost of up to $2.2 billion, or 2,100 percent increase!
The original estimated cost for restoration of Long Island Rail Road service on the old Rockaway LIRR branch began at $600 million, and has grown to $1 billion over the past two years.
Release of the final planning study for this project was scheduled for June 2017 and postponed to December 2017. Don't be surprised if the estimated cost for this project has doubled.
No one from the MTA or Department of Transportation can tell you the source for funding environmental reviews, final designs and construction for either project.
I predict both projects will fail to progress beyond simple planning feasibility studies due to lack of financing. The only winners will be consultants who were well paid by taxpayers in preparation of both reports.
