I know of dozens of babies that were named after cars. (And jeeps!) But this is the only one I know of that was named for a highway exit:
Susie and Dan McLaughlin of Meadville, Pennsylvania, were expecting a baby boy in the summer of 1998. When Susie went into labor, they got into Susie’s sister’s car and began heading toward the hospital via I-79. The baby wasn’t willing to wait that long, though, so they pulled over next to Erie County’s McKean exit and Susie gave birth in the back seat. The baby was named Keane after the exit.
