Service on the Long Island Rail Road (LIRR) Main Line will be disrupted during a weekend in November so the MTA can perform infrastructure work, the agency said on Monday — impacting the primary rail service between New York City and Nassau and Suffolk Counties.

LIRR crews will perform signal upgrade work on the Main Line from 12:15 a.m. Saturday, Nov. 8, to 2:15 a.m. Monday, Nov. 10.

The agency said the work will require major service adjustments on the Main Line, resulting in service changes on the Oyster Bay, Port Jefferson and Ronkonkoma Branches, and schedule adjustments on the commuter rail’s other branches.

The Carle Place, Westbury and Bethpage stations will be closed.
