A woman was killed today crossing an Upper West Side intersection with groceries in her arms – mowed down by a sports car that tried to flee the scene, witnesses and sources said.

The victim – who wasn’t immediately identified – was fatally struck by a white Dodge Charger at about 4 p.m. while crossing West 93rd Street at its cross with Columbus Avenue, according to witnesses.

“It was so loud that I heard it from my window. I heard the thud,” said H.A. Rigney, who lives in a building near the tragic accident scene. “She was thrown 20 feet from the crosswalk. Her feet were bare.”

The victim was rushed to St. Luke’s Hospital, where she was pronounced dead.

The female driver is in custody and charges are pending, police said. The Charger’s windshield was smashed afer slamming into the pedestrian.

“She was laying there like a ragdoll,” Rigney added. “All of her groceries were all over the street and her shows were knocked off.”

The driver continued on for about a block before stopping at Columbus and Amsterdam Avenue after a good Samaritan in a green Jets jacket ran after her and yelled for her to stop, witnesses added.

“It was my light. It was my light,” the driver sobbed on a cell phone video shot by another witness.
