CHICAGO -- A shooting on the Eisenhower Expressway had traffic backed up for miles overnight.
The shooting happened just after 10 p.m. Thursday on the outbound Eisenhower between Cicero and Laramie avenues.
A man was driving a silver Sedan when he was shot in the leg. His injuries are not life-threatening.
The shooting caused a big backup on the outbound side of the expressway as police examined the scene -- looking for shell casings and other evidence.
A driver who was stuck in traffic after the shooting says they were caught off guard by the situation.
"It's almost past midnight and I was wondering why there was traffic at this time I checked my phone and I realize there was an accident. Turns out it was a shooting so that's kind of scary right on the 290 and now the entire highway is shut down," said Hamad Hussain.
The Eisenhower has since reopened.
No one has been arrested.
Police do not know at this time whether it was a targeted or random shooting.
