Two New Bridges Coming to East Hampton – Service Changes Start Today

In the final stretch of work, Long Island Rail Road crews starting today will replace two 124-year-old bridges in East Hampton.

The Accabonac Road and North Main Street Bridges, separated by about 500 feet, were constructed in 1895: The North Main Street Bridge is the westernmost bridge and currently has a posted clearance of 10 feet; the Accabonac Road Bridge has a posted clearance of 9-feet-9-inches. These low-hanging bridges have been the site of many accidents over the years due to trucks striking the bridges.

Construction activities for this project began in August 2018. Last month, the LIRR completed construction of three of the four retaining walls required to raise the tracks at the Accabonac Road Bridge in East Hampton. This phase of construction, running through November 10, will require service changes and road closures. Details can be found below.
The roadway clearance for vehicles traveling underneath these bridges will be higher with the installation of the new single-span steel bridge structures – their new height clearance will permit trucks to safely pass underneath these bridges. Accabonac Road Bridge and North Main Street Bridges will be the sixth and seventh major bridge-related projects to be completed on Long Island since the beginning of June.

Foundation shaft installation 9/6/2019.

Service Changes
Buses will substitute for all train service east of Southampton, which includes Bridgehampton, East Hampton, Amagansett and Montauk, on a 24/7 basis between October 15 and November 10; additional maintenance work will be performed on the weekend of October 26-27 – during this weekend, the busing program will be extended from Hampton Bays through Montauk.
Customers should expect additional travel time, and earlier westbound departures to allow connections with train service at Southampton. Additionally, North Main Street and Accabonac Road have been alternately closed with road detours that began Wednesday, Oct. 2.

Road closures during the final phase of the North Main Street and Accabonac Road Bridge Replacement Project are as follows:

  • Friday, October 11: North Main Street reopened
  • Friday, October 11 to Monday, October 28: Accabonac Road Closure – Detour onto Collins Avenue and Route 27 to reach North Main Street
  • Sunday, October 27: Sunday, November 10: North Main Street Road Closure – Detour onto Collins Avenue and Route 27 to reach Accabonac Road

Please note road closures may be extended due to weather conditions and other work-related circumstances. While the work is in progress, MTA and East Hampton Police will assist with road closure and traffic detours. The entire MTA October 11, 2019 press release is available here.
