AMES, Iowa (AP) – Iowa is warning drivers to stay away from roads, bridges and ramps that are closed by flooding along the Missouri River because it’s against the law and dangerous. The Department of Transportation on Tuesday reminded  motorists that signs, barricades, fencing and other devices where roads have been closed are there for a reason – to protect the public.

Officials say even if water is not currently flowing over a highway, the road could be damaged or there could be other risks ahead making it unsafe for travel. According to the department, a little as 6 inches of moving water can knock you off your feet, while 2 feet of floodwater can float a car.
