SIOUX FALLS, S.D. – The South Dakota Department of Transportation has closed the bridge on Highway 11 over Split Rock Creek located about two-and-a-half miles south of Brandon.

Southbound traffic on Highway 11 is being detoured to Madison Street and northbound traffic is being detoured on Highway 42.

The water levels of Split Rock Creek continue to rise and when they reach a certain threshold, the department closes the structure to monitor the material in the bed of the channel for erosion.

The department asks motorists to be aware of flooding and to not drive through floodwaters or go around barricades, the road may be washed out underneath.
