The Bollman Truss Railroad Bridge at Savage, Maryland, United States is the only surviving example of a revolutionary design in the history of American bridge engineering. The type was named after its inventor, Wendel Bollman , a self-educated Baltimore engineer.
A Howe truss is a truss bridge consisting of chords, verticals, and diagonals whose vertical members are in tension and whose diagonal members are in compression. The Howe truss was invented by William Howe in 1840, and was widely used as a bridge in the mid to late 1800s.
The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.
A continuous truss bridge is a truss bridge that extends without hinges or joints across three or more supports. A continuous truss bridge may use less material than a series of simple trusses because a continuous truss distributes live loads across all the spans; in a series of simple trusses, each truss must be capable of supporting the ...
The Waddell "A" Truss Bridge is standardized truss bridge design that was first patented in 1893 by prolific civil engineer John Alexander Low Waddell. The design provided a simple low-cost, high-strength solution for use by railroads across the United States and Empire of Japan for short spans of around 100 ft (30.5 m).
The bridge was initially over 270 metres (890 ft) long, although numerous shortenings over the years and river bank replenishments mean the bridge now totals only 204.7 metres (672 ft) long. It is the oldest surviving truss bridge in the world, consisting of strutted and triangulated trusses of moderate span, supported on piled trestles; as ...
The Belfast truss is a cross between Town's lattice truss and the bowstring truss. It was developed in Ireland as a wide-span shallow rise roof truss for industrial structures. McTear & Co of Belfast, Ireland began fabricating these trusses in wood starting around 1866. By 1899, spans of 24 metres (79 ft) had been achieved, and in the 20th ...
The Charles M. Braga Jr. Memorial Bridge, also known as the Braga Bridge, or simply, The Braga, is a through truss bridge that carries Interstate 195 over the Taunton River between the town of Somerset and the city of Fall River, near the mouth of the Quequechan River at the confluence with Mount Hope Bay.
