A significant crash involving a semi-truck that was carrying ammunition has resulted in the closure of I-94 through the Lowry Hill Tunnel in Minneapolis. The accident occurred when the semi struck a wall, causing it to split apart and spill its load. This incident has led to the closure of the interstate between I-394 and I-35W, with traffic cameras capturing the moment of the crash. While one side of the tunnel reopened two hours later, the roadway remains partially closed as crews continue to respond to the aftermath and manage backed-up traffic resulting in a medical emergency. Multiple reports are highlighting the severity of the situation, including videos of the crash and its immediate aftermath.
