When Michigan State Police learned of a man threatening to jump from a highway overpass early Tuesday, they came up with a novel way to help him. They shut down all lanes of I-696 in Oak Park around the overpass, in both directions, and called in 13 semi-trucks that were passing through the area. The trucks lined the highway underneath the overpass so that if the man did jump, his fall would be shortened, Fox 2 reports. Negotiators spoke to the man for several hours and ultimately he walked off the bridge. Police took him to a nearby hospital for evaluation. (More Michigan stories.)
