Updated: Sign warns Illinois drivers about zombies

KSDK -- Drivers in the Metro East were warned about zombies during their Tuesday morning commute.

This happened on 1-255 Southbound just south of the Pontoon Beach exit. Someone changed IDOT's sign to read "DAILY LANE CLOSURES DUE TO ZOMBIES."

IDOT believes someone hacked the sign's computer remotely. While crewmembers were still on the scene after fixing the message, the display changed back to the hoax.

"We've talked to the company that supplies these and they have a patch out there they've applied to the program to fix the problem," said Joe Gasaway with the Illinois Department of Transportation.

Just last week, drivers in Austin, TX were warned about "Nazi zombies, run!" and "The end is near." Pranksters there cut the padlock on the sign and changed the message.
