Dozens of vehicles were involved in two large pileups on a snowy Interstate 40 in Tennessee on Friday afternoon.

The pileups occurred between mile markers 116 and 120 on the westbound lanes of I-40, around 1 p.m.

The pileups will likely keep the highway closed for considerable time, however details about the expected length and time of the closure aren’t currently available.

Here’s what it looks like at the scene.

Truck driver Jeffrey Mount shared the following footage to LiveTrucking’s Trucker Feed Facebook group, taken near mile marker 120.

Update (4:54 p.m.):

Police say at least 16 tractor trailers were involved in the pileup.

As of 4:54, the road remains closed, and officials have declared a state of emergency. Authorities are advising drivers to stay off roads in middle and west Tennessee if possible.

“Do not risk damaging your vehicle, getting injured or even killed. This is not a game of slip and slide. It is very dangerous to drive on ice,” Tennessee Highway patrol says.

Update (1/13/2018 11:52 a.m.):

No major injuries were reported in the large pileups, however drivers were stranded overnight in the westbound lanes. Traffic is slowly starting to move on Saturday morning as TDOT crews work to clear the I-40 westbound lanes.
