The tagline for Gov. Andrew Cuomo’s agenda this year is “Built to Lead,” and in some ways it’s an apt description.

In January he unveiled a long list of infrastructure projects. Some, like an overhaul of the dilapidated terminals at LaGuardia International Airport and an agreement to fund the Metropolitan Transportation Authority, were already in the works. Others, like a third line on a busy stretch of the Long Island Rail Road and a new Penn Station, face serious obstacles.

But in the state budget, Cuomo secured funding for a number of the projects while trying to balance downstate transit needs with investments in upstate roads and bridges.

In this special section on transportation infrastructure, City & State explores which projects are likely to move forward – and the various challenges they will face.
