Nassau Boulevard Bridge Replacement Project

The Nassau Boulevard Bridge Replacement Project is scheduled to begin on Monday, June 24. The Nassau Boulevard Bridge, a low-hanging bridge, has been the site of many accidents over the years, resulting in train delays in both directions while LIRR crews worked to determine the bridge's safety and structural stability before restoring train service.

Slated to be removed and replaced with a three-track structure, the Nassau Boulevard Bridge Replacement Project is expected to be complete at the end of October 2019.

Beginning on Monday evening, from approximately 7 pm to 3 am, one lane of Nassau Boulevard will be closed. Flaggers and signage will direct drivers to proceed north and south in an alternating fashion along the remaining open lane. In order to minimize disruptions during the busy daytime hours and to accelerate the completion of this project, the initial demolition will occur in the overnight hours for approximately the next two weeks.

For the majority of the time, as long as the crews can maintain safe and reliable operations, traffic lanes will remain open during the four-month construction period. As this will be an active construction area and to ensure the safety of drivers, pedestrians and workers, there will be occasional, unavoidable partial and full road closures. Additionally, at least one pedestrian sidewalk under the bridge will remain accessible during the construction period.

As always, please visit for more information about the project. If you have an immediate question about the work in your community, please email the project or call the 24-hour Hotline at 516-203-4955.
