old highway flatbed trailers work.
old railroad flat cars work.
old platform log bodies work.

start calling truck dismantling places and junk yards around you, somebody has got to have something. hemlock logs for abbutments. pick a tree on the other side of the river to set a pulley up in. run a nice long rope or cable from the bridge to the pulley, then back across the river to a vehicle.

we have used this technique for log bodies and timber bridge panels.

I have no idea what regulations may be in your area, but knowing just some of the regulations in NY would make me want to find out what is allowable first. From there the most cost effective or just effective bridge can be built.  JMO though.

Good Day, another idea that we have used was we demolished an old quarry, and recycled the scale and skelton under neath it. Turned out good as i think it was 53' long. HTH, JoeB

For a permanent streaming crossing, plastic culverts covered with fill are a good option.  Galvanized will eventually rust and cave in.  Also run a hydrology study to size the pipes to handle the flow including a emergency over flow to handle big storms.  A culvert crossing with fill dirt is the same as the dam of a pond except you are not storing water with a stream crossing.   Bigger  or more pipes may seem like an over kill, but it will prevent an washout during a 50 or 100 year storm.  And do get the blessings from all your environmental agencies.

I appreciate all the responses! Environmental agencies aren't a concern. I live in E. Ky where there is no zoning, and 1/4 of the "septic systems" are still run "over the hill" ;D  I think that my ADS culvert would be my mist cost effective means. With the price of scrap around here any large piece of metal is either higher than groceries, or already chopped up and gone to the scrap yard.
