temperature fluctuations could have led to metal fatigue in a steel bridge. To resist Goat Canyon's high winds, it was built with a 14° curve. Additionally, the bridge was built without nails, using bolts instead. Construction was completed by 1933, leading to a realignment of the railroad route. For fire suppression a tank car was located near tunnel 16. After World War II, the San Diego and Arizona Eastern Railway was impacted by increased automobile travel. In 1951, scheduled passenger service over the trestle ended. Intermittent freight traffic continued when the railroad was not closed due to damage. In 1976, Hurricane Kathleen damaged the trestle, as well as the rest of the line; repairs were not completed until 1981. Use of the railroad ended again in 1983 due to collapsed tunnels. In 1999, Huell Howser visited the trestle and filmed an episode about it for the public television series California's Gold. Restoration of the railway did not resume until 2003. During the 2003 Cedar Fire, crews working on the railway repairs assisted the California Department of Forestry by extinguishing fires set by arsonists along the railroad tracks. The Carrizo Gorge Railway resumed service on the line after repairs were completed in 2004. Pacific Southwest Railway Museum provided trips on the railroad from Campo. In 2008, the Desert line, which includes track north of Mexico including Carrizo Gorge closed indefinitely for repairs, ending revenue rail usage of the trestle. In early 2017, tunnel Number 6 near the trestle collapsed, and the route was obstructed. In January 2018, Baja California Railroad assessed the line hoping to repair it to allow it to return to operation, but efforts to repair the line had been abandoned by 2021. The trestle remains a popular destination for hikers. Surrounding environment Goat Canyon is a valley in San Diego County, California. One feature of the canyon is it has a dry waterfall. The land, which forms the canyon, is crystalline basement. Since at least the 1970s, there has been a population of bighorn sheep, an endangered species, living near the trestle. Another endangered species in the area of the trestle is the Bell's vireo. During a desert bloom, which occurred in 2017, monkey flowers were observed flowering in the canyon.
