LONG ISLAND, NY — An additional 75 rails cars were deployed this week to help bolster Long Island's artificial reefs, Gov. Andrew Cuomo said. Artificial reef expansion helps to restore marine habitat and grow tourism and recreation opportunities, he said. Seven rail cars were added to the Shinnecock artificial reef and four rail cars to the Moriches reef, he said. The final deployment of 2020 brings the total number of rail cars added to reefs in New York to 75 for the year.
