Construction for the expansion of the LIRR Main Line bridge over the Meadowbrook Parkway in Carle Place is well underway and is expected to be completed on schedule this fall. Part of MTA Construction & Development’s LIRR Expansion Project from Floral Park to Hicksville, this component the project consists of constructing new abutments and center piers to support an additional bay for a third track.
The bridge has been in service since 1956 and will maintain its current 13’ 2” clearance, since commercial traffic such as tall trucks are not permitted on the parkway. The New York State Department of Transportation owns the Meadowbrook Parkway bridge.
To date, crews completed support of excavation work for abutments and excavation for abutment footings. They currently are reconstructing abutments. Center piers on the island dividing the six-lane parkway will begin soon and is scheduled to be completed in late summer, followed by construction of the bridge for the third track, expected to be completed this fall.
A total of eight bridges, including the Linden Avenue pedestrian underpass in Floral Park, will have been replaced or expanded as part of the LIRR Expansion project. Once the Meadowbrook Parkway bridge expansion is complete, only the Tanners Pond Road/Denton Avenue bridge remains to be replaced and is scheduled for construction and completion next year.
Other components of the LIRR Expansion project include elimination of eight under grade crossings, rebuilt stations, new switches, substations and new track over a 10-mile long corridor between Floral Park and Hicksville. The project will reduce train congestion and delays, enable true bi-directional service during peak hours, enhance safety and improve the quality of life for communities along the corridor.
