LULING, La. (AP) — A tugboat crash into a Louisiana bridge led to the sinking of two barges of grain in the Mississippi River. News outlets report the tugboat identified as Cooperative Spirit collided with the Luling Bridge early Sunday. Two of the 29 barges being pulled by the tugboat sank. No injuries have been reported. A portion of the river was closed after the crash. A vessel with the same name was involved in a fatal crash with another tugboat earlier this year. It's unclear whether that was the same tugboat that crashed Sunday.
