For months, residents of Margo Drive, a narrow residential street on the outskirts of Charlotte, N.C., have puzzled over this question: Why do gigantic semitrucks hauling cargo for Amazon keep rumbling down their one-lane, dead-end road?

While Amazon has a warehouse nearby that opened late last year, its entrance is located through an impassable thicket of trees about 613 feet away from the end of Margo Drive. Despite that, semitrucks with Amazon’s smiley-face logos have repeatedly had to abort their trips down the road, gouging the grounds around Garden Memorial Evangelical Presbyterian Church as they backed out of the street. At other times, Amazon trucks have knocked down a light pole and gotten stuck for hours on the road.
