“If one of these tunnels were to fail, Wright says, the economic implications for New Jersey would be dire. But he says the impact would ripple up and down the East Coast — through Boston, New York, Philadelphia, Baltimore and Washington.”

Two century-old rail tunnels connect New Jersey to New York. They were badly damaged by the corrosive salt water that Sandy filled them with. Shutdown or failure of one would wreak havoc, not just on commuters who would endure hours of delays, but also on the already busy roads as commuters sought other ways to get to work. Business up and down the Eastern seaboard would also be crippled as goods and workers would be delayed. It would be a #commutapocalypse.
