It wouldn't surprise me. I recall watching a video about researchers trapping and tagging raccoons to study their movements. What they found is that the territories of individual urban raccoons were rather small, and bordered by hazards like busy roads. So, if a busy road is sufficiently dangerous to be an individual's boundary, I'd not be surprised if things like highways through the city made for boarders for larger groups and populations of raccoons.
