In order to finish the Second Avenue Subway by its December deadline, the MTA requires an additional $10 million per month on top of the $39 million per month that is currently being spent, Kent Haggas, the project’s independent engineer, has told DNAinfo.

About seventy-percent of the project goals set forth by the MTA in March have been reached, according to the project’s contractors. According to another engineer, a pileup of changes that arose during construction have also heightened the stress to complete the subway on time.

In February, the MTA’s full board voted to use $66 million from its existing contingency budget to stay on schedule, leaving $50 million left to finish the project.

On Tuesday, Governor Cuomo announced the Capital Plan Review Board’s approval of the MTA’s $25 billion repair and upgrade plan, according to an article from the Daily News: “The money covers everything from track and station repairs to new train cars and buses.” Included in that range is the next phase of the Second Avenue Subway project into East Harlem.

The Daily News article quotes a statement from Governor Cuomo: “By investing in the most robust transportation plan in state history, we are reimagining the MTA and ensuring a safer, more reliable and more resilient public transportation network for tomorrow.”

The state will contribute $8.3 billion while the city will contribute $2.5 billion but the funding will not be available until the MTA has exhausted its own $50 million slotted for the subway.
