Commuters looking to drive into Manhattan should avoid the Queens-Midtown Tunnel at all costs, as a drilling mistake Wednesday led to water leaking into the tunnel and closing down both tubes for hours, snarling traffic for miles.

A contractor working for the New York City Economic Development Corporation mistakenly drilled a small hole in the outer casing of the tunnel while doing preliminary work on the East River Esplanade around 12:30 p.m., according to a spokesperson. From that 2.5-inch hole on the outside edge of the tunnel, water was able to get into the south tube via the ventilation ducts, the spokesperson said, and leak onto cars passing through.

A video posted by one driver to Facebook showed the leaking water splash across his windshield.
