Stop in for a cup of coffee

Hey I need a bridge idea. Thinking of trying to find an old dock door plate??
We have several small springs run through the property. They are always running never dry up.
It's a pain to drive through them muddy mess.
I have a great spot side to side is about three feet.
Just looking for something to support a max of 1000 pounds riding mower or golf cart.

If you have trees/logs around then corduroy road can work... not as long lasting as steel or iron, but can be inexpensive if the resources are laying around
