A 30 year old Utah man was killed in a single vehicle crash on I-80 Monday morning about 1 mile east of Cheyenne. The Wyoming highway patrol says James Castleman of South Ogden, Utah was eastbound and was pulling double van type semi trailers.  For reasons unknown, his combination went off the roadway into the median in a slight right hand curve where it then went through a barbed wire fence. The entire tractor trailer combination then overturned in the median and it slid into the westbound lanes of travel coming to rest in and blocking both westbound lanes.  Evidence indicates that Castleman attempted to brake the combination and steer back onto the roadway just prior to the rollover.  Castleman was partially ejected from the cab during the rollover and was pinned in the wreckage.  He was declared dead at the scene. the co-driver, identified as Tracy Sherrod of Clinton, Utah, was in the sleeper berth at the time of the crash.  He was hospitalized at Cheyenne Regional Medical Center.
