Nice bridge. I think you should add wing walls before you backfill.

Looks great. What are you going to do when the big logs for the main supports rot out, though?

Nice bridge. I am going to begin a 20-24' bridge across a crevasse withing the next few months, hopefully. Maybe I will look to your pictures for ideas. I am thinking 10' wide.

Get a flatbed semitrailer and pull that across after cutting off the landing gear and the wheels.

The wood piece of the deck are easy to replace, the wood part under them are harder to replace, but they are in treated wood and they dont have a strong strutural role.

Any reason why you didn't use treated wood for the deck?

Because it cheapper to put down three Hemlock tree cut them in 3 inch beam and threated myself with a brown stuff (or in fact by my wife!). ...But it take more time!

I've seen old rail cars used as bridges. Also old van trailer frames.

You are right, the next bridge on that stream is an old van trailer, but I have not fund a proper size cheap one! So I made it with an old garage overhead steel frame... a lot more work!
