Two pedestrians were struck and killed within a few hours of each other in Manhattan, including a kindergarten teacher who was on her way to work early Monday, police sources said.

Udeshi Shruti Sundeep, 51, was crossing the street at Third Ave. and E. 76th St. on the Upper East Side just before 6:40 a.m. when an Audi sedan made a right turn onto Third Ave. and struck her, police said.

Medics took her to Lenox Hill Hospital, but she couldn’t be saved.

The Audi’s driver, Connette Bercik, 59, of Oldwick, N.J., stayed on the scene. Police charged her with failure to yield to a pedestrian and issued her a desk appearance ticket.

Police sources said Sundeep worked at a private school nearby. She lived about a block and a half away from the scene of the crash.

Just over five hours later, about 11:50 a.m., a 43-year-old woman was struck and killed by a white Nissan van as its driver, 45, turned onto W. 93rd St. from Amsterdam Ave. on the Upper West Side, police said.

Police sources described the woman as homeless, and said she was known to lie down in the street. Witnesses saw her lie down right before the van hit her, the sources said.

Medics took her to Mount Sinai Morningside Hospital, but she couldn’t be saved. The van’s driver stayed at the scene.

Cops are still investigating both fatal crashes, and haven’t yet released the name of the victim in the Upper West Side crash.
