An elderly woman was killed as she tried to cross notoriously dangerous Queens Boulevard on Saturday night, authorities said.

The woman, in her 60s or 70s, was struck by a vehicle as she crossed against the light at 71st Street, cops said.

The victim, whose name was withheld pending family notification, died later at Jamaica Hospital.

“It’s one of the worst places for pedestrians in the city,” a police source said of Queens Boulevard.
