Construction puzzle -- with answer

On our drive to Salt Lake City, we saw structures like this a couple times.


What are they building?

At first I couldn't figure out what they were building. There was no need for an overpass since there was no road trying to cross the freeway. The arches looked like something that might provide shade for a traffic stop that you would see crossing the border.

Then we saw the structure below.

land bridge for wildlife to cross to freeway

Betty and I both realized at that point they were building land bridges to allow wildlife to get from one side of the freeway to the other without having to dodge cars going 80 miles an hour.
