Metro-North Begins Replacement of Two Bridges in Patterson Bridges on Upper Harlem Line from Monday, Sept. 16, Through, Friday, Nov. 15

Buses to Substitute for Certain Off-Peak Trains Between Wassaic and Southeast to Accommodate Infrastructure Improvement

MTA Metro-North Railroad advises customers that the first phase of the replacement of two bridges in Patterson, located between Wassaic and Southeast on the Harlem Line, gets underway on Monday, Sept. 16, continuing through Friday, Nov. 15. Both bridges are located in an area known as the “Great Swamp,” with no road adjacent to the track. Crews will begin work constructing a temporary access road into the site. The road needs to be in place before crews can begin the actual replacement work. Once the new bridges are in place, the access road will be removed and the area restored to its original condition. Metro-North crews will take advantage of this outage to weld track and cut brush.

To accommodate this crucial infrastructure work, starting on Monday, Sept. 16, and continuing through, Friday, Nov. 15, buses will substitute for select off-peak trains between Southeast and Wassaic on the Harlem Line.

Service details are below:

Southbound to Southeast
Buses will substitute for the 9:47 a.m., 11:47 a.m., 1:41 p.m., and 3:41 p.m. trains from Wassaic to Southeast, making all scheduled stops at the following stations: Tenmile River, Dover Plains, Harlem Valley-Wingdale, Pawling and Patterson.

Bus service will operate 20-40 minutes earlier than normally scheduled train times. Buses will connect with regularly scheduled trains at Southeast for continuing service to Grand Central Terminal.

Northbound to Wassaic
Buses will substitute for the 9:33 a.m., 11:35 a.m., 1:33 p.m., and 3:33 p.m. trains from Southeast to Wassaic, making all scheduled stops at the following stations: Patterson, Pawling, Harlem Valley-Wingdale, Dover Plains, Tenmile River and Wassaic.
