Cambridge Flat, Vintage American
The Cambridge Flat bridge is a Warren Truss girder bridge that is formed by a top chord with a parallel chord (flat) geometry. This truss eliminates verticals at the top chord panel points. It has a sturdy look and is a great choice for multiple span bridges or bridges set in different settings.
Many communities are benefitting from the advantages of the Cambridge Flat, like Mafia Island in Tanzania. U.S. Bridge completed this project in 2012 and since then the island’s overall economic and tourist industries have been positively impacted. The bridge has improved shipping, primarily for the commercial fishermen of the island, and has resulted in Mafia Island becoming a major tourist hub in the Indian Ocean region.
A Bridge Built to Last
The truss design is a welded or bolted Warren truss configured in the Cambridge Flat style as manufactured by U.S. Bridge. This bridge features a top chord with a polygonal shape. The design is also known as a camelback. Attractive and efficient, this steel bridge is ideal for both city and country locales. Builders can choose from one, two, and three-lane options with a width range between 12 and 44 feet.
The trusses each have a horizontal top chord, two diagonal members in each truss panel, and a vertical member at each interior bottom chord panel point. The bottom (tension) chord of each truss consists of two equal-sized members with adequate section properties to provide redundancy.
