Hardhat fights for life after hit on Gowanus

A construction worker was clinging to life Saturday after being struck by a drunken driver while he put out cones on the Gowanus Expressway, police said.

The 64-year-old hardhat had just blocked off a westbound lane near the entrance to the Belt Parkway by Exit 22 at about 4:30 a.m. when Jordan Perez, 25, inexplicably drove into the lane the construction worker had just closed off and rammed into him.

The victim sustained a massive head injury and was rushed to NYU Langone Hospital-Brooklyn in grave condition, officials said.

Cops took Perez into custody and later charged him with vehicular assault, drunken driving and reckless endangerment. His arraignment was pending Saturday afternoon.

Mangled cars are evidence of vicious collision on the Gowanus Expressway that critically injured a construction worker.
