@ 75 ft it would be nearly impossible to span with a wide flange. 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.
