We've just passed the fifth anniversary of Superstorm Sandy, which inflicted over $70 billion in damage when it slammed into the northeastern U.S. in 2012. Among its victims was New York City's extensive network of car and subway tunnels, many of which were completely flooded with corrosive salt water that took days to drain. It was weeks before functionality was restored, and five years later, the city is still repairing the damage. So officials have decided to get proactive and prepare for the next storm—hence the apocalyptic-looking zombie floodgate.

According to ABC 7 News, the city's Metropolitan Transit Authority has completed the installation of four 25-ton floodgates, one for each opening of two major car tunnels that connect the island of Manhattan to the boroughs of Queens and Brooklyn. Both the Queens Midtown tunnel and the Hugh Carey Tunnel were totally filled with storm surge, and preventing a repeat of that when the next superstorm inevitably hits was a high priority. That's why the gigantic doors are designed to withstand a surge four feet higher than Sandy's.
