The Long Island Rail Road (LIRR) expansion project is part of a comprehensive plan to transform and expand New York’s vital regional transportation infrastructure. The project extended 9.8 miles between the Floral Park and Hicksville stations, where five branches converge carrying approximately 40 percent of LIRR’s daily ridership. IMEG provided civil engineering design services for the expansion, including utilities coordination efforts, and was also actively involved in public outreach.

The scope of work consisted of the construction of 9.8 miles of third track and the elimination of seven street-level train crossings, also known as grade crossings. The project included sound walls to reduce noise, station upgrades, and additional parking structures. The addition of a third track will increase track capacity through the corridor, making it easier to run trains, improve service reliability, provide two-way peak travel, reduce existing noise levels, and make transit more attractive.

The project also included clearing and grubbing, utility relocation, and related railroad infrastructure, including ties, switches, cable, signal equipment, utility poles, and other items needed to support railroad operations.
