Oregon replaced a highway bridge in a few days.

And a few miles north, they moved the old bridge to the side so a new one could be built in its place, while the old bridge stayed in use.

I saw them put a bridge over a highway about 80 miles south of here. They built it off to the side, then rolled it out over an existing road in a weekend. It was impressive.
