A crash involving a tanker has shut down I-55 from milepost 72-80 between Divernon and Farmersville both northbound and southbound. Traffic is being rerouted to a frontage road as the Interstate is completely shut down.  Motorists are urged to take alternate routes.  There is no word on when the interstate will be reopened.  High wind speeds have made visibility a concern in some areas of the area. Ambulances from four counties including Christian, Montgomery, and Sangamon have been sent out and there are multiple reports of helicopters on the scene to help evacuate. According to State Police, Divernon City Hall is currently being used as a reunification point for families.   We will have more on this developing story throughout the day.
