Coney island subway yard completes major flood protection project

The Metropolitan Transportation Authority announced the completion of a comprehensive flood protection system at the Coney Island Yard in Brooklyn. The multiyear engineering effort aims to safeguard the massive rapid transit maintenance facility from future coastal storms and extreme weather events.

Fourteen years ago, Superstorm Sandy inundated the property with tens of millions of gallons of saltwater, halting operations at one of the largest rapid transit yards in North America. The storm flooded the one-hundred-acre yard under roughly two feet of water, severely damaging tracks, signal systems, and critical electrical equipment.

To prevent similar destruction, builders constructed a perimeter flood wall and a reinforced concrete barrier equipped with a storm-activated flood door. The newly finished defense system also incorporates eight large swinging structural steel vehicular gates, stackable barriers across four railroad tracks, and two pedestrian access gates.

Engineers also built a four-thousand-foot elevated bridge to maintain operational capabilities during high water events and secure rolling stock. The total cost of the protective infrastructure reached approximately five hundred million dollars, matching figures provided in agency oversight reports. Construction personnel logged six hundred twenty-five thousand work hours without a single lost-time accident or recordable incident throughout the multiyear build.

This initiative follows similar coastal defense projects across the regional transit network, including resiliency upgrades completed at the Long Island City Yard and coastal surge protections along the Rockaway Line. The agency reported that it has invested more than seven billion dollars in total system hardening since Sandy. Transit officials will test the automated gate seals and drainage pumps during the upcoming quarterly maintenance review.
