Winter weather wreaks havoc on roads and schools in SD and MN.

Strong winds and recent snowfall have caused blizzard-like conditions and icy roads in South Dakota, prompting the closure of I-29 and I-90 in parts of the state. Several accidents have been reported due to near zero visibility. No Travel Advisories have been put in place on secondary highways throughout South Dakota, and travelers are urged to avoid using them to avoid interstate closures.
