I didn't see a roll away option either. The way I see it you need 2 things; a drawbridge and a remote control. Or just put in a bridge with a gate on the end and can lock it up so no one can use it. It should be easy to get a permit for a bridge. It doesn't do anything to the creek like culverts do.

 

Well one thing we did not think of of he gets a permit for a bridge then more than likely he is going to have to submit a engineered drawing for the bridge..

 

I never thought about that at all. To put in culverts he might need to pay someone to do an environmental impact study. That would be even more of a problem.

 

Not necessarily... a few clubs I know that have used culvert for water study just had to show a well detailed plan to conservation or similar and they were able to get it signed off ...

 

I decided to cross in another spot, and make a simple bridge from 4 2x6x16's with some cross peices for decking. Here its a bit narrower. The disadvantage is that I won't be able to drive along the tree line in the spring because it will be too wet and damage the marsh. And I'm giving up on the idea of getting a car in there.
They won't provide a permit because they don't approve of using the recreational trail as an official/permanent way to access property. Although everyone else does it. If they did they would have to wide the road, assign addressing, etc.

Same 14ft board in another spot

 

I think I'd use something beefier than 2x6's.

 

Hopfully you are flipping those on edge when building your crossing

 

Personally, for that kind of span I'd put 2x12's on edge to bear the weight of a quad and rider. I'd do 4 of them spaced about 16" apart and run the decking a couple inches wider on each end.

 

 

Thanks, yes I was planning to put them on edge. I'll use something wider (taller) than 2x6 like you said.
