Crews are now working on the sixth and final under-grade crossing of the LIRR Expansion Project. LIRR New York Gov. Andrew Cuomo announced that the Metropolitan Transportation Authority’s (MTA) LIRR Expansion Project is closing the Main Street railroad crossing in Mineola. It marks the final LIRR Expansion Project grade crossing that is being eliminated. Since construction began on the LIRR Expansion Project just over two years ago, grade crossings at Covert Avenue and S. 12th Street in New Hyde Park, New Hyde Park Road in Garden City, two crossings at Willis Avenue in Mineola, School Street in Westbury and Urban Avenue in New Cassel also have been closed.
