I am considering purchasing a property next to a river. This property is remote.
Of course I would like to cross an atv to the other side. So I have been contemplating ways to make a cable bridge.
River is approximately 70 yards wide with steep 8ft banks.
Entering river is prohibited.


I have seen several old one lane metal bridges, but realistically they are overkill weight wise and not really long enough without extensive refabrication.

So for the engineers, what diameter of cable could be stretched across with decking over the cables.
