You will have to use a truss at that span
Ok. I think I know what a truss is. But I'm not entirely sure what a truss is....
Even if I could find trusses 100 feet long (like where they're tearing down a building or something) how would I haul them?
And, old railcars are 89 feet long. And they just drag them into place and they're rated for 180,000. Aren't they just steel beams?
I'm trying to support basically just pickups and tractors. 20,000 pounds total weight. Not log trucks.

Trying to keep the budget in mind, I don't see a way that you will be able to span 75 clear feet for less than the price you were quoted. With that being said i would also be hesitant to trust an old rail car with supporting 10 tons at that span, but that may just be the conservative engineer in me. Perhaps another OBer will chime in with some more insight into other options. If no answers come by the morning I will take a look when I get to my steel manual tomorrow.

With all due respect, if you don’t know what a truss is you probably have no business building a bridge yourself. I mean this isn’t a walk path over a pond. You don’t want this thing collapsing while you’re in a vehicle driving across. Death is a shitty consequence for saving a little cash.
Just looking out for ya, OP.

Ever been to a Walmart and looked at the ceiling?
