The Goteik viaduct was a railway trestle over the Goteik Gorge of the Myitnge River in western Shan State, Myanmar. The bridge was between the two towns of Nawnghkio and Gokhteik, and it was part of the railways between Pyin Oo Lwin, the summer capital of the former British colonial administrators of Burma, and Lashio, the principal town of northern Shan State. It was the highest bridge in Myanmar and when it was completed, the largest railway trestle in the world. It was located approximately 100 km northeast of Mandalay.
