Company says it’s cooperating in investigation of Mississippi bridge collapse that killed 3 workers

MENDENHALL, Miss. (AP) — A construction company says it is cooperating with an investigation of how a bridge in rural Mississippi collapsed while some of its employees were preparing the structure for demolition. Three employees of T.L. Wallace Construction were killed and four were injured Wednesday when the bridge collapsed over the Strong River in central Mississippi’s Simpson County. Sheriff Paul Mullins says one of the injured workers was treated at the scene and the other three remained hospitalized in critical condition Thursday. The bridge was on state Route 149, about 40 miles south of Jackson. It was closed to traffic since mid-September as part of a bridge replacement program.
