Indiana State Police say a crash involving two semi tractor-trailers closed southbound lanes of Interstate 65 in Tippecanoe County just south of Lafayette shortly before 8:30 this morning Eastern time. No injuries were reported. The crash occurred at the 163 mile marker. Southbound traffic was being diverted onto State Road 38. Traffic caught between the wreckage and State Road 38 was being allowed around the crash scene on the emergency berm. Troopers say the interstate was closed due to a large amount of wreckage covering both southbound lanes.
