[AT] How To Build A Bridge--Off Topic

[charlie hill]

This bridge located about 35 miles north of me was built that way.
It crosses a couple of miles of wetland and then nearly 1 mile of river.
After they cut the large trees in the wetland the bridge crew never
touched the ground again except for the pilings being driven in the
ground from above.
