Any one know what is the max length that you can get in pre-stressed concrete beams.
A neighbor of mine who owned the land on on side of a river is after buying the land on the other side of the river and is thinking of putting a bridge across the river for both cattle and machinery. The river is aprox 30 feet wide, so in reality the beams would need to be 45 feet long to reach safely back to support pillars on each bank to support them.
Would planning permission be required to fit this overpass, this is a salmon and trout river and would have the banks regularly patrolled by the fisheries,
