The 78 - year - old bridge along South Gregson Street provides only 11 feet 8 inches (3.56 m) of vertical clearance . It cannot be raised, because nearby railroad crossings would also have to be raised with it . The street also cannot be lowered, because a major sewer line runs only four feet (1.2 m) under Gregson Street . </P> <P> Despite numerous signs and warning devices, a truck crashes into the bridge on average at least once a month . Most crashes involve rental trucks, even though rental agencies warn renters about the under - height bridges in the area . </P>
