Indiana State Police have identified the driver of a semi tractor-trailer who was killed when his semi overturned Thursday afternoon on the city's southeast side.

46-year-old Nathaniel James of Southfield, Michigan was on the ramp from westbound I-74 to northbound I-465 when his semi overturned.  James was pronounced dead at the scene and State Police say speed may have played a factor in the crash. No one else was involved in the crash.

The ramp was closed for several hours as police investigated the crash. Crews also spent several hours cleaning up a fuel spill on the ramp.
