A Warren Truss Bridge Necklace


The Warren Truss Bridge is designed after the Route 66 Meramec Bridge near St. Louis, Missouri that is on the National Historic Landmark Register and endangered of being demolished.   25% of the profits of the sale of this necklace will be donated in support of this important bridge.  Full information about this project can be found on the Route 66 Meramec Bridge page.  

This necklace is available in gold-toned brass or shining stainless steel.  The 2” pendant hangs gracefully from a gold fill or sterling silver chain.

In the design of the necklace, the structural elements are simplified with effort given to retaining the essence of the form.  The engineering behind the structure of the bridge is incredible and complex, and the design beautiful and inspiring.  This literal truss shape is available in brass or stainless steel in a 2” pendant. 

This specific design is the warren truss with verticals.

The Warren truss was patented in 1848 by its designers James Warren and Willoughby Theobald Monzani, and consists of horizontal sections joined only by angled cross-members, forming alternately inverted equilateral triangle-shaped spaces along its length.    This truss design combines strength with economy of materials and can be relatively lightweight.  Warren truss construction has also been used in airframe construction for aircraft since the 1920s.
