A Council Bluffs Public Works employee was seriously injured this morning while filling potholes below the I-80 bridge on Madison Avenue.  

Police say the employee was attempting to stop traffic as crews filled potholes.

When one car stopped, another vehicle rear-ended the first vehicle and hit the worker.  

The worker suffered a broken pelvis, and the driver that was hit from behind suffered minor injuries.  The driver that didn't stop was issued two citations.
