Water flooded the Queens-Midtown tunnel shortly after noon Wednesday after an apparent construction accident, snarling traffic in the heart of the city.
Sources told the News that a construction crew working on a project adjacent to the tunnel accidentally drilled a small hole into the tunnel, leading both tubes to flood.
A spokesperson for the MTA, which operates the tunnel, said there were no injuries.
The tunnel remained closed Wednesday afternoon, as crews worked to reopen on tube.
Traffic was gridlocked across the area as motorists sought alternate routes.
