A UPS truck slammed into a tollway's concrete median outside Chicago Tuesday, killing the driver.

Police said the semi was traveling southbound on I-294 in Hinsdale when the driver somehow lost control. The truck was pulling two trailers, one of which overturned.

The driver, identified as 61-year-old Glen Dantuma, died at a nearby hospital, Fox 32 reported. Investigators said they would take a closer look at what triggered the crash.

Crews reopened all lanes of traffic after several hours Tuesday morning. Hinsdale is roughly 20 miles west of Chicago.
