REPORTER: Construction on the 2nd Avenue subway will break ground on April 12th, according to the MTA. The long-awaited subway will eventually carry passengers from 125th Street to the Financial District. MTA Chief Executive Elliot Sander says the project will pick up where the agency left off in the 1970s, when 3 sections of tunnel were built before funding ran out.

SANDER: We'll be doing it in the 2nd Avenue Subway tunnel, a part of it that has been constructed it is in pristine condition.
