Crash granny saved by her seat belt

A Long Island grandmother survived this horrific Brooklyn car wreck yesterday — and is living proof that seat belts really work.

Marie Barnett, 84, was cruising through Midwood at around 5:30 a.m. when her gray 2008 Honda Accord jumped the curb and smashed into the back of a Brooklyn College building, officials said.

The Merrick woman had to be cut from the twisted steel by emergency responders, and was rushed to Kings County Hospital with several broken bones.

Barnett, who sources said had a pre-existing heart condition, was wearing a seat belt at the time of the accident.

“It’s a miracle she has survived,” said her daughter, who declined to give her name.

“But she really hasn’t survived yet, because her heart is not doing what it’s supposed to do.”

The daughter was shocked by the crash, insisting her elderly mother is “a slow driver.”

Teary-eyed relatives were huddled at her bedside yesterday, but most were too distraught to talk.

The accident happened shortly after Barnett dropped off a friend at a train station.

She was heading past the college on Campus Road when she lost control of the vehicle.

The impact sent Barnett’s car flying into the back of Gershwin Hall, a performance center that is undergoing renovations.

No one was inside the building at the time.

Gershwin Hall will be demolished sometime next year to make way for Tow Hall, a new performance space set to open in 2014.

In Merrick, Barnett’s neighbors on a quiet block said the friendly old lady lives alone, but is frequently visited by relatives.

“She always says hello and goodbye. I hope she is going to be OK,” said Shelly Abrams, who lives a few doors down Sherman Avenue.
