In June, Jack and I went south on the Alaska Highway to camp and came across this construction site with a new culvert going in. More info on the photos. Click on the first one and scroll to the right.
This is the culvert that’s going in, about 6 feet in diameter and maybe 80 (?) feet long.
Jack says this is the stream water being diverted while the construction is going on.
Water is being sprayed to keep the dust down.
The fabric is Typar that was laid down under the road years ago and there’s also some rigid foam insulation showing on the right. All of this is an attempt to keep the dirt under the road frozen in order to prevent frost heaves.
The next two photos are pretty self explanatory. Collapsed culverts are very common in interior Alaska.
