WATCH: Trucker encounters a different type of traffic jam

One trucker encountered a different type of traffic jam in this interesting video. 

In the clip, a massive group of animals can be seen crossing a major roadway all in a line. 

Are they elk? Deer? Horses? You decide. Whatever they are, they took over the road for at least several minutes as a line of truckers waited for them to cross. 

“The biomass is changing lanes,” captioned the video poster. 

Check out the mass crossing, below.
