Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid
A licensed engineer can help operators design a safe, appropriate timber bridge. Personnel from Virginia Tech have described in detail how to build a stringer bridge using standard bridge design procedures, for example, by placing timber stringers across the abutment, using a bent to support a trestle or timber frame. Their methods are quick ...

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. It consists of parallel timber logs laid across timber pile bents. [1] These were by far the most common bridge type built in the state of Colorado, for example, historically. [1]

A trestle bridge is a bridge composed of a number of short spans supported by closely spaced frames. A trestle (sometimes tressel) is a rigid frame used as a support, historically a tripod used to support a stool or a pair of isosceles triangles joined at their apices by a plank or beam such as the support structure for a trestle table .
The Cottonwood Creek Bridge is a bridge in Fallon County, Montana near the town of Ismay, built in 1934. It was listed on the National Register of Historic Places in 2014. From 1926 to 1941, at least 1,242 timber stringer bridges were built in Montana; this is one of very few intact surviving bridges.
