A chain-reaction wreck Tuesday morning on U.S. 50 in western Jennings County left a 24-year-old man with a leg injury, police said.

That injury to Aaron Sanders of North Vernon occurred when he drove into cement dumped on the road from a cement mixer, also involved in the wreck, Jennings County Officer Kevin Hall said.

Sanders was transported to Schneck Medical Center in Seymour, and his condition was not available at press time.

The wreck was reported at 8:43 a.m. in the 9600 block of West U.S. 50 in front of Biehle Electric Inc., which has a Seymour address but is located in western Jennings County.

The wreck caused the closure of both lanes of U.S. 50 for more than two hours. Both lanes reopened to motorists at 11:23 a.m.

The incident that led to the wreck began when a Lee’s Ready Mix cement mixer being driven westbound by Derick Pendleton, 33, of Seymour rear-ended a semitrailer driven by Nathaniel Cole III, 38, of Spring, Texas.

Cole’s truck was pushed forward onto flatbed trailer pulled by a Ford F-350 driven by Cody Owen, 26, of North Vernon. Owen was westbound waiting to turn left into Biehle’s Electric Inc.

That collision caused cement from Pendleton’s truck to pour out onto the roadway where it was struck by Sanders’ semitrailer, which was headed east.

“About a yard or yard-and-a-half of material came out pretty heavy and struck an eastbound semi,” he said, adding that was the semi driven by Sanders and the cab and trailer were both damaged.

Personnel with the Indiana State Police, Spencer Township Volunteer Fire Department and North Vernon Fire Department assisted at the scene.
