  • Full M subway Service Restored between Metropolitan Av
    and 71 Av in both directions

    • Rush hour J subway Z subway skip-stop service is restored between Marcy Av and Broadway Junction
    • Daytime peak direction J subway express service between Marcy Av and Myrtle Av is restored
  • Accomplishments

  • The new Myrtle Viaduct and Fresh Pond Bridge replaced two 100-year-old structures. Key features of the completed project include:

    Myrtle Viaduct

    • New 310-foot viaduct utilizing low vibration track (LVT), which reduces noise impacts to the public and nearby homes
    • 29 pre-engineered concrete and structural steel sections installed
    • 122 piles installed for the precast pedestals and structural steel columns
    • Removed 736 cubic yards of concrete during demolition of the original viaduct and piers

    Fresh Pond Bridge

    • New 65-foot single span plate girder bridge supported by new concrete abutments and bearings
    • 154 tons of structural steel and 165 yards of concrete used
    • 36 piles installed for the foundation
    • Replaced 600 feet of track and third rail at and around the bridge
  • The M subway Line Infrastructure

  • Safe and reliable subway service depends on a network of tracks, bridges and other structures that are in a state of good repair.

    To meet the needs of M subway subway train customers, MTA New York City Transit undertook a two-phase plan to address the urgent infrastructure needs on the Myrtle Av line. This critical work involved complete demolition and rebuilding of the Myrtle Viaduct, and the Fresh Pond Bridge (completed in September).

    About the Myrtle Viaduct

    The 310-foot-long Myrtle Viaduct is a critical link for 50,000 weekday trips on the M subway subway. The two-track, concrete elevated right-of-way connects the Myrtle Av M subway and Jamaica J subway Z subway subway lines, enabling M subway customers to travel between Queens, Brooklyn, and Manhattan. Built in 1913, the original viaduct served New Yorkers for more than 100 years. While regular monitoring and critical maintenance had permitted ongoing service, the inevitable end of the viaduct’s useful life was fast approaching. The aged concrete deck had suffered major deterioration, and the tracks and structure needed to be replaced.

    A full suspension of M subway subway service over the Myrtle Viaduct was the only option due to the nature of the work, construction site constraints, and other challenges.

    The Fresh Pond Bridge

    In Ridgewood, Queens, the M subway subway had been relying upon the 100-year-old Fresh Pond Bridge to cross over the New York & Atlantic Railway's tracks.  Phase 1 of work addressed the bridge’s replacement. The new Fresh Pond Bridge is now raised in height, and features new steel columns, decks, drainage, third rails and low vibration tracks.

    While not as expansive as the Myrtle Viaduct, the bridge links the Fresh Pond Rd M subway subway station and the Metropolitan Av M subway subway terminal.  Not only is this a bridge between stations, it also permits access to the subway car storage yards that are critical to providing service.
