An Upper West Side philanthropist who was nearly killed by a shopping cart that was tossed by teens from an overpass won a $45.2 million jury award Friday — and said she plans to donate a portion of the money to a local youth center.

Victim Marion Hedges, 53, shook with emotion when the verdict was announced — but she didn’t shed a tear because a side effect of her brain damage is the inability to cry.

She then stood and applauded the jurors before they left Manhattan Supreme Court.

“It’s been a long, long road,” Hedges said.

Hedges and her son were buying Halloween candy for poor kids on Oct. 30, 2011, at the East River Plaza mall in East Harlem when the teens tossed the cart from a 79-foot-high landing outside a Target store.

Hedges suffered severe brain injuries when the cart knocked her to the ground. But she never blamed Jeovanni Rosario, 13, and Raymond Hernandez, 12, who were behind the incident. Both teens were sentenced to time in juvenile facilities.

“I just want to be able to do something with the money that helps kids in Harlem, I really do,” Hedges said after the verdict, specifying that she’d like to support the Johnson Community Center on East 113th Street.

“We want to help Harlem kids have a chance to do something besides throw a shopping cart on a boring Sunday afternoon,” she said.

The judge was wowed by the Manhattan mom’s attitude throughout the case.

“I think you have shown us all how to live in the face of adversity,” Justice Carmen St. George had said at the end of the trial.

Hedges, her son, Dayton, and her husband, Michael, sued Target, the mall and its security company for negligence in 2011, saying the businesses ignored past incidents involving kids fooling around with carts.

The Hedgeses previously settled with Target for a confidential sum.

The six-person jury found the teens 10 percent responsible for Hedges’ injuries while assigning 65 percent of the fault to the mall and 25 percent to Planned Security Services.

Jurors awarded Hedges $40.7 million, her 19-year-old son $2.5 million and her husband $2 million. Dayton Hedges testified that he still has nightmares about the incident, and his father said he has become more of a caretaker than a husband.

One juror, Joel Walker, told The Post that “money can’t buy back what she’ll be missing the rest of her life.

“This was a horrible, horrible incident that happened to Mrs. Hedges and her family,” said Walker, 43.

The jurors reached the verdict after just three hours of deliberating following a four-and-a-half-week trial.

The defendants plan to appeal.
