I have seen various pics in books where pontoons are anchored in place and or powered by what appear to be outboard motors against a current. Debris floating down a river, things dislodging, careless truck drivers etc can all render a bridge u/s unless you have engineers on hand to keep things just right.
Are all bridges built by engineers considered pontoon bridges?
