MTA Long Island Rail Road (LIRR) crews will spend 30 days this summer building heavy concrete slabs that will serve as the ceiling of a new underpass at the Harold Interlocking switching complex in Sunnyside, Queens, as part of the East Side Access "mega-project."
The underpass is designed to create a congestion-free bypass for Amtrak trains approaching Penn Station from Boston, LIRR officials said in a press release.
To accommodate the work, LIRR will cancel five rush-hour trains each day from July 22 to Aug. 16. The trains' stops will be added to other trains that'll depart within five to 15 minutes of canceled trains' departure times. Four other trains will operate shortened runs.
