A 70-year-old man crossing a Brooklyn intersection was killed Thursday when he was hit by a city garbage truck, witnesses and cops said.

Frank Negron was pinned underneath the truck on Flushing Ave. near WilsonAve. in Bushwick for several minutes until the FDNY pulled him out.

He was rushed to Elmhurst Hospital Center after the 4:15 p.m. crash and died minutes later, said cops.

"He was under the truck," said onlooker Johnny Majia, 23. "He had a lot of blood on his face."

The driver and his partner, who both had started their jobs in August, were taken to Wyckoff Heights Medical Center visibly traumatized by the crash, said a Department of Sanitation spokesman.

Cops said it was unlikely that the driver would face charges.

Witnesses said Negron was a longtime Bushwick resident who was on his way to buy a cup of coffee.
