Federal officials announced the release of $215 million in previously promised grant money for the $8-billion East Side Access project, which is to be completed by 2019.
"This new installment of federal funding represents a strong commitment to this vital project for Long Island commuters and the thousands of construction workers employed in moving it forward," Bishop said in a statement.
Schumer said in a statement that the release of the money "signs, seals and delivers on our promise to maintain funding for" the project.
The federal government has already kicked in $2.6 billion toward East Side Access. The MTA is also hoping for a $2.2-billion federal loan for the project, which will connect the LIRR to Grand Central Terminal through newly bored tunnels in Manhattan and Queens.
