bridge for Island
You might want to look for a curved truss from an old airport hanger. You can do a lot with these type trusses available in wood or steel. Good concrete bases and about three or four run and you should be safe for any thing that might be six foot wide.

bridge for Island
Chief thats a good strong bridge when built with a tractor trailers frame that's the way we've been using them to put across streams for snowmobile trails. We've even butt welded two for wider streams and cross them with 10.000lbs machines. We set them with excavators on the wheel ends and just extend the front by chains to cross. It might be a frame would also work. Still not as nice looking as just the arches from a roof of a warehouse.

We picked up some from a 60 foot wide building that had an arch built into them of about ten foot on that length. We cut in half to make transporting easier as well as we at the time had no need for them at that length, they were 2by four laminated together five high or deep. They are not the best for NY winter weather but we've had some in about ten years now and still crossing with the 10,000lb groomers. We set them up at about 16" spacing and the bridges are 12 foot wide. The arch for on streams with spring conditions makes it nicer then the flat bridges that catch tree's and limbs and then back up. We were given these trusses as nobody else seemed to want them. We've had oppertunities to pick up more but the open wood is not going to last as long as metal and we are looking at 17,000lb groomers for the new ones and we feel we need more capacity.

They aren't very strong to begin with and the metal is light and tough to work with. I'd put what ever configuration together that works off the main rails and test it with the load on it before making the span. If you could have it raised you could cable it underneath for additional capacity.

The home frame I believe would do fine for that load and all the outer rails would be able to be removed. Remember that the homes frame are supported thru out the length.

Speaking of wastes it wasn't but a month ago but the head of the transportation from our congress has a couple of new bridges that will be near record for helping so few as welll as the cost. This bridge is much the same a bit of over kill but so is what our government doing!

You should have a good base to sit them on so they will stay dry.
