I’ve seen people use a house trailer frame but you’d need to be careful about what you drove over that with. Also, not sure if that would get you to 75 feet or not.

Was in the forestry/timber/logging industry for 43 years. Would never attempt to cross an obstacle over 50’. I preferred culverts, logs and fill first. Sweet gums were found to be the best trees for crossing a span. They are very long and straight, are slightly flexible. They make the best railroad ties because of their
Flexibility. Then we would board the span. I always wondered if creosote stadium poles would be good for a long crossing. Then board. A large stadium pole could have 20-30 feet laying on each side of the obstacle. I have no idea of the cost. Just a thought. Also some sort of cable bridge (ATV or walking only). I have seen these used for access over long/wide obstacles. Just walk.
