Goat Canyon Trestle is a wooden trestle in San Diego County, California. [1] At a length of 597–750 feet (182–229 m), it is the world's largest all-wood trestle. [1] [8] [10] [11] Goat Canyon Trestle was built in 1933 as part of the San Diego and Arizona Eastern Railway, after one of the many tunnels through the Carrizo Gorge collapsed.
It was finished in December 1906 and, at that time, was the longest rail trestle in the United States and the third longest bridge of its kind in the world. It has 18 towers for support. Other trestles constructed since that time are longer, such as the Hi-Line Railroad Bridge in Valley City, North Dakota, which is 3,860 feet (1,180 m) long.
Some bridges are measured from the beginning of the entrance ramp to the end of the exit ramp. Some are measured from shoreline to shoreline. Yet others use the length of the total construction involved in building the bridge. Since there is no standard, no ranking of a bridge should be assumed because of its position in the list.
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 Lethbridge Viaduct, commonly known as the High Level Bridge, is a railway trestle bridge over the Oldman River in Lethbridge, Alberta, Canada.Constructed between 1907 and 1909 by the Canadian Pacific Railway, it is the largest railway structure in Canada and the largest of its type in the world, and is still regularly maintained and used over a century since its construction.
The bridge's dimensions measure 44 m (144 ft) high and 188 m (617 ft) long, making it the largest wooden trestle in the Commonwealth of Nations and one of the highest railway trestles in the world. [2] It was constructed out of old-growth Douglas fir timbers, [3] and has an unusual seven-degree curve. [4]
The LaBranche Wetlands Bridge is a concrete trestle bridge in the U.S. state of Louisiana. With a total length of 7,902 metres (25,925 ft), it is one of the longest bridges in the world. [1] The bridge carries Interstate 310 over the LaBranche Wetlands [2] [3] in St. Charles Parish. The bridge opened in 1992.
