The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid
Using fallen trees, stringer bridges can be built. Wood laminated by stress, glued, dowels, or nails lumber are good for panel bridges.

The bridges are also known as Little Lithodendron Bridge and Lithodendron Bridge. A timber stringer bridge was the cheapest way to span spaces like arroyos.
