A 66-year-old woman was killed when the driver of a pickup truck rammed into her as she pushed her toddler granddaughter in a stroller in a Brooklyn crosswalk on Tuesday afternoon, police said.

The 2-year-old girl miraculously suffered only scrapes and bruises as a result of the 1:10 p.m. crash in Bath Beach that left her grandmother mortally wounded, authorities said.

The grandmother, who was not immediately identified, was crossing 25th Avenue when a Dodge Ram made a turn onto Bath Avenue and struck her, cops said.

She suffered head trauma and was brought to NYU Langone Hospital-Brooklyn, but could not be saved, authorities said.

The tot was taken to Maimonides Medical Center, where she was listed in stable condition, cops said. 

The truck driver, a 56-year-old man, stayed at the site of the crash until police arrived.

It was not immediately clear whether he would face criminal charges.

Both the driver and the vehicle were properly licensed and sobriety testing was underway, police sources said. 

The NYPD’s Highway District Collision Investigation Squad is probing the crash.

Photos showed a host of items from the tragic grandmother-granddaughter outing strewn in the roadway – including a pink mesh bag, a beige hat, a tiny blue shoe and the blue stroller.
