The MTA LIRR Expansion Project Floral Park to Hicksville team had a busy 2019! Here’s a timelapse video of the major milestones completed this year:

“We have four more existing bridges to replace and six more at-grade crossings to eliminate over the next 35 months,” said MTA Chief Development Officer Janno Lieber. “The LIRR Expansion Project is moving forward at an extraordinary pace, which is why it is the model project for how we are changing the way we manage large capital projects to do them smarter, faster and better.”

Here’s a look at the five bridge replacements completed in 2019 by the numbers!

Cherry Lane Bridge in Carle Place (June 1-2)

  • New 320-ton bridge was moved into place with a Self-Propelled Modular Transporter (SPMT)
  • Cherry Lane Bridge is now 14 feet high, helping to reduce bridge strikes
  • Original bridge was 66-years-old

Urban Avenue in New Cassel (July 20-21)

  • 1st time in U.S. history the innovative horizontal jacking method was used to install a railroad bridge
  • More than 16,000 cubic yards of material excavated
  • Newly-constructed bridge weighs 1,200 tons

South Tyson Avenue Bridge in Floral Park (August 17-18)

  • Took approximately 2,000 hours for crews to construct and install the bridge (pushed and positioned into place with a SPMT)
  • Approximately 107,000 commuters travel across the bridge every day

Covert Avenue in New Hyde Park (new bridge at previous railroad crossing – August 24-25)

  • Crews built a 2,600-ton concrete structure onsite that includes the rail bridge, 40 feet of roadway beneath the bridge, and the side walls
  • After crews removed the existing rail tracks and dug down 25 feet, this concrete box structure was moved incrementally more than 50 feet into perfect position

Nassau Boulevard Bridge in Garden City (October 5-6)

  • Replaced bridge was 108-years-old
  • With a low clearance of 11’6”, this bridge was struck 16 times in 2018 and 2019 alone
  • Bridge was successfully replaced in just 55 hours
  • New bridge weighs 285 tons

The holidays are here, but the MTA will be working throughout the winter. “We are keeping this pace up over the next 34 months because we have four more bridges to replace and six more at-grade crossings to eliminate in that time,” said Lieber. Stay up-to-date with weekly updates by signing up for our A Modern LI on – and expect the project to achieve more milestones soon!

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 station accessibility improvements, 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.
