Due to accumulating heavy snow and sustained high winds causing blizzard-like conditions and extensive drifting, Interstate 90 has closed eastbound and westbound from Chamberlain (exit 265) to Sioux Falls (Marion Road/exit 395), while Interstate 29 northbound and southbound has closed from the I-29/I-90 interchange in Sioux Falls to Brookings (exit 132) as of 8:45 a.m. today, according to the state Department of Transportation.
DOT snow plows are having difficulty clearing roads due to near zero visibility and accumulating snow, with some plows becoming stuck with the high accumulation of snow on the lanes of traffic.
DOT anticipates the I-90 and I-29 closures to remain in place throughout the day. Conditions are expected to improve this afternoon. Officials will continually assess conditions to determine when I-90 and I-29 can be reopened safely.
No-travel advisories are also in place for numerous state highways in the central and southeastern portion of South Dakota with some becoming impassable. Motorists are asked to avoid travel as blizzard-like conditions are making travel hazardous.
