INDIANAPOLIS (AP) -- A semitrailer has overturned on an Indianapolis interstate, spilling what police say are 45,000 pounds of packages of butter and other dairy products. The crash happened about 3:30 a.m. Friday in the eastbound lanes of Interstate 465 just west of its interchange with Interstate 65 on the city's south side. The crash left perhaps thousands of butter tubs strewn on the highway, many broken open and coating the roadway. Police say the truck driver apparently fell asleep and hit a highway barrier. No injuries were reported. Some lanes of the highway are expected to be closed for hours for cleanup work, with crews using a small front-end loader to scoop the butter tubs and whipped cream containers into large trash bins.
