The ice bridge, that is the official government approved extension to the highway, has not yet been "built." But people have been moving across the frozen river for some time. At first by foot, and carefully.

One way to get across is by skijoring. You put on some skis, and hook up your sled dogs to your body. "Now, help me with this zipper thing would you?"

Skijoring is an actual winter sport and can be done with a horse, a dog, or dogs. It originated in Norway where it is spelled with more letters and dots over some of them.
