The Goteik viaduct (မြန်မာဘာသာ. ဂုတ်ထိပ်တံတား, also known as Gohteik viaduct) is a railway trestle in Nawnghkio, western Shan State, Myanmar (also known as Burma). The bridge is between the two towns of Pyin U Lwin, the summer capital of the former British colonial administrators of Burma, and Lashio, the principal town of northern Shan State. It is the highest bridge in Myanmar and when it was completed, the largest railway trestle in the world. The bridge is located approximately 100 km northeast of Mandalay.
The bridge was constructed in 1899 and completed in 1900 by Pennsylvania and Maryland Bridge Construction. The components were made by the Pennsylvania Steel Company, and the parts were shipped from the United States. The rail line was constructed as a way for the British Empire to expand their influence in the region. The construction project was overseen by Sir Arthur Rendel, engineer for the Burma Railroad Company.
The viaduct stretches Шаблон:Convert from end to end with 15 towers which span Шаблон:Convert along with a double tower Шаблон:Convert long. The 15 towers support 10 deck truss spans of Шаблон:Convert along with six plate girder spans Шаблон:Convert long and an approach span of Шаблон:Convert. Many sources have put the height of the bridge at Шаблон:Convert. This is supposedly a measurement to the river level as it flows underground through a tunnel at the point it passes underneath the trestle. The true height of the bridge as measured from the rail deck to the ground on the downstream side of the tallest tower is Шаблон:Convert. The cost of the bridge construction was 111,200 £(Pound sterling).
Due to its technical and natural condition it was considered as a masterpiece of the world standard.
As the line from Mandalay to Lashio is of strategic value a diversionary route to the valley floor was built in 1976 - 1978, to keep trains running even if the Goteik viaduct was sabotaged. Its tracks were still visible from the viaduct in 2013, but the line has been left to the tropical vegetation since 2002.
The bridge was mentioned in Paul Theroux's acclaimed travelogue The Great Railway Bazaar. He described the viaduct as "a monster of silver geometry in all the ragged rock and jungle, its presence was bizarre".
