Hi
I need to build a Pond bridge the total length needs to be 11ft and 2ft wide .It also needs to be flat not arched .It will be the only access to the rest of the back garden so will be used regularly.
I was thinking of using the grooved decking panels for the panels you will actually tread on as eventually we are having decking put in up to the pond .
But the actual gap where the bridge will get no support from underneath is 5ft going over the pond .It then goes over a thin strip of ground so the bridge needs to be quite long to get to a very very firm ground base .Thats why im saying 11ft .
So the question is what supports would be strong enough for this to just nail decking planks to ? .Would decking posts do at 4x4 inches or would these bow a little ,it needs to be totally rigid .
