TULSA, Oklahoma -- People driving westbound on I-44 near the Lewis exit were warned to be on the lookout for zombies Thursday.

Authorities say someone apparently got access to the control unit of a portable sign board in the construction area of I-44 and made some changes to the message.

For several hours early Thursday the sign flashed a warning about zombies ahead.

So far no zombies have been reported in the area.
