Man killed in Eisenhower Expressway crash after suffering ‘medical emergency’

A man was died Sunday after suffering a medical emergency on the Eisenhower Expressway on the West Side and crashing into several other cars.

Byron McClain was westbound on Interstate 290 about 1:35 p.m. when he suffered an “unknown medical emergency” and crashed into a concrete barrier, Illinois State Police said.

McClain, 47, veered into oncoming traffic and struck two vehicles, state police said. He then struck a light pole before swerving back into the westbound lanes and hitting a third vehicle, according to state police.

McClain was taken to a hospital, where he was pronounced dead, state police said. Autopsy results were pending, according to the Cook County medical examiner’s office.

All westbound lanes reopened about 4:15 p.m.
