UPDATE: South Dakota DOT closes more of I-29 and I-90 due to worsening conditions

Snow road closed by MGN.

PIERRE, S.D. (KSFY) UPDATE 9 PM:

Officials are closing Interstate 90 from Mitchell to Sioux Falls and Interstate 29 from Brookings to Sioux Falls, effective immediately.

I-90 is now closed from Rapid City to Sioux Falls and I-29 is closed from the North Dakota border to Sioux Falls.

Officials says conditions are quickly deteriorating in the eastern part of the state as the expected blizzard moves in. Heavy snow and strong sustained winds are making their way east creating hazardous driving conditions due to icy, snow-packed roads and very limited visibility.

As this storm system moves through, more interstate closures and No Travel Advisories can be expected. Based on the National Weather Service forecast, it is highly likely I-29 from Sioux Falls to the Iowa border will close sometime during the overnight hours tonight or early Saturday morning.

UPDATE 4 PM:

State officials have also closed I-29 from the North Dakota border to Brookings.

This follows the closure of I-90 from Rapid City to Mitchell earlier on Friday.

Officials says conditions are quickly deteriorating in the northeastern part of the state as strong winds and heavy snow are creating zero visibility conditions and snow packed/icy roadways in much of the area.

UPDATE 2 PM:

State officials have closed Interstate 90 from Rapid City to Mitchell.

The interstate was earlier closed from Rapid City to Murdo.

ORIGINAL STORY:

Officials have closed Interstate 90 from Rapid City to Murdo, both east and westbound.

Heavy snow and strong winds have made safe travel impossible in this area. Motorists are strongly cautioned that other roads in area will likely become impassible as this storm continues throughout the day.

Officials are also asking drivers to stay put and not plan any travel across the state for the rest of today and into the weekend. As this storm system moves through, more interstate closures and No Travel Advisories can be expected.
