6. One of the Largest Construction Projects in New York History is Underway by the NYC DEP
New York City Water Tunnel #3 has been under construction by the NYC Department of Environmental Protection for thirty years. It was authorized in 1954. According to the DEP, it is one of the largest capital projects ever in New York City and will allow the city to inspect its tunnels #1 and #2 for the first time in history. The tunnel will be over 60 miles long, starting at the Hillview Reservoir in Yonkers. The first 13 miles, already in service, goes from Yonkers through the Bronx, into Manhattan across Central Park, and crossing the East River into Astoria, Queens. The Brooklyn section, which is 5.5 miles long, starts in Red Hook, with a connection to Staten Island, and runs through Park Slope, Bushwick, Bedford Stuyvesant, and to Maspeth in Queens where it will connect to Astoria.
Construction is set to be finished in the year 2020.
