Just before noon, a black Tahoe and a gold Subaru crashed in the middle of the intersection.
The impact sent the Tahoe onto the sidewalk, wrapping it around a pole and hitting 59-year-old Beata Kurpiewski and her three-year-old grandson, as they walked to his pre-school.
The child in critical but stable condition.
Neighbors say it's a dangerous intersection, with a history of bad accidents.
