The Long Island Rail Road (LIRR) has announced that it will replace switches at Mill Road in Peconic on December 12, 2017, along the Main Line stretch between Ronkonkoma and Greenport. The project is part of the Mill Road Switch Replacement Project.
Due to the work, the LIRR will take the single main track out of service between Ronkonkoma and Greenport. Buses will be substituted for trains in this area. Regular train service will resume between Greenport and Ronkonkoma the morning of December 13.
Information on the service changes is available on the rail tab of the “Service Status” box at the left side of MTA’s website.
