Multi-Ringed Arches
While the typical stone arch bridge consists of an arch built with one ring of thick stones, it is possible to build a stone arch bridge with multiple arch rings to create a thick arch with relatively small stones.

Retaining Walls: Failure and Repairs
The retaining walls (spandrels and approaches) in a stone arch bridge are prone to failure thanks to their relatively thin width. However, there are several things that can be done to repair and prevent these failures.

Retaining Walls: A Weak Point of Stone Bridges
Stone bridges use retaining walls as part of the structure to hold the roadway. These walls are a decided weakness, due to their relatively thin width. In this post we investigate these walls and related design possibilities.

Why Were Stone Bridges Built?
Stone arch bridges were usually built historically for their proven durability, which made these structures desirable. In the early 1900s, stone bridges made a resurgence in the United States.

Planning the Falsework
The formwork is important to arch building. It must be designed to handle the weight while maintaining the correct shape, and must be planned for easy removal without damaging the arch.

Efficiently Designed Stone Culverts
Building stone arch culverts can be difficult to do without using a disproportionately large amount of material. In this post several ways the efficiency of design can be increased are discussed.

Designing the Span
A wide variety of design options are available to the builder of a stone arch bridge. Here are some considerations that are helpful to keep in mind when narrowing down the design.

Clues to the Past: Cowley’s “New” Stone Bridges and the Oak Valley Culverts
A comparison of the Oak Valley, Elk County, Kansas, culverts with many of those in Cowley County, Kansas, suggests there were quite a few stone bridges built by local governments independently of the WPA in the 1930s.

The Oak Valley Stone Bridges
In Oak Valley Township, Elk County, Kansas, we found eleven little-known stone arch bridges. Most of these structures are culverts, and their unique characteristics make these bridges quite noteworthy.
