The Goat Canyon Trestle is a wooden trestle in San Diego County, California. It measures 597–750 feet in length and is only 15 miles from the Mexican border. It is the world’s largest freestanding wooden trestle in the world. 
It was designed by the Chief Engineer of the San Diego and Arizona railroad. The Goat Canyon Trestle was built in 1933 to replace a tunnel running through the Carrizo Gorge after its collapse. 
Its construction began in 1932, after sections of the trestle were arranged beneath the canyon, then lifted into position because of the temperature change. The trestle was made of wood instead of metal and was built with a 14-degree curve to withstand the high winds. The bridge was also constructed without nails and completed in 1933. A tank was located near the tunnel for fire suppression.
However, in 1976, despite the trestle being damaged by Hurricane Kathleen, it completed its repairs in 1981. The railroad lost functionality in 1983 due to the collapse of tunnel roads. It began operations after another series of reconstructions which was completed in 2004.
The Carrizo Gorge Railway is closed down at the moment, and efforts made to repair the project were abandoned in 2021.
