An MTA train halted at the 125th street station in New York

The MTA has approved its historic $51.5 billion capital spending proposal for 2020-2024. Board members in attendance Wednesday voted unanimously.

The plan marks a 70 percent increase over the transit agency's previous four-year plan, and its largest one ever by far, as part of an aggressive effort to repair the agency's aging infrastructure and accelerate service enhancements for the millions of New Yorkers who use its public transit system on a daily basis.
