Work Begins at Plainfield Avenue Bridge Modification in Floral Park

Plainfield Av Bridge 12-13-19

Support of excavation work has begun for the new Plainfield Avenue bridge in Floral Park, one of several bridges that have been or will be replaced as part of the LIRR Expansion project from Floral Park to Hicksville. Once this phase of construction is complete, work will start on the bridge abutment.

The Plainfield Avenue Bridge will receive a new single-track span to accommodate the additional track with the LIRR Expansion Project. In service since 1958, this 12’-9” bridge has been the site of many accidents over the years by trucks striking the bridge, resulting in train delays in both directions while LIRR crews worked to determine the bridge’s safety and structural stability before restoring train service. The new bridge’s height clearance of 14’ will allow trucks to safely pass underneath. Work on the Plainfield Avenue Bridge follows the completion by the MTA of five major LIRR bridge projects in 2019 alone.

The bridge is expected to be completed by the end of spring 2020. For more information and construction photos, please visit the Plainfield Avenue Bridge Modification project page on

The construction of a third track from Floral Park to Hicksville will reduce train congestion and delays and enable true bi-directional service during peak hours with a more reliable rail network. This transformative work includes several related projects, including the construction of parking garages, retaining walls, improvements to rail bridges and the removal of eight street-level grade crossings. Construction is being managed to minimize the impact on daily routines, with extensive mitigation and public outreach efforts in local communities.
