A school bus crash that killed a pedestrian yesterday in the Upper East Side occurred at a notoriously dangerous intersection, with low visibility due to construction.

While the cause of the crash is still being investigated, neighbors told the Daily News that the driver appeared to be racing the traffic signal when he struck a woman crossing 2nd Avenue at East 93rd Street around 3:30 p.m.

“The bus was traveling westbound and trying to get through a yellow light before it turned red," a witness told the tabloid. "The bus driver didn't see the pedestrian. He was looking straight ahead trying to make the light."

Assemblyman Dan Quart referred to the intersection as one in which lanes "essentially melt into one another and very narrow, tight sidewalks and crosswalks." He added that the intersection is "inherently difficult and dangerous, and today was the greatest of tragedies in the area."

According to data from Transportation Alternatives, the intersection has been the site of six driver/pedestrian injuries and one cyclist injury in the past two and a half years.

The driver of the bus was reportedly so impacted by the crash he had to be removed by paramedics. “He was a mess. He fell inside [the bus] and they had to pick him up. He looked all dazed and was wobbly," an onlooker told the Post.

The bus was carrying six children home from the nearby St. Stephen's of Hungary School. None of the children were reported to have been injured. The victim—a woman said to be in her 40s—was pronounced dead when the paramedics arrived.
