The Goteik viaduct, located in Nawnghkio, is one of Burma’s most stunning engineering marvel. Built by the colonial British in the beginning of the 20th century, this spectacular railway bridge is the highest bridge in Myanmar and when it was completed, in 1900, it was the largest railway trestle in the world.
The viaduct stretches 689 meters from end to end supported by 15 towers. Many sources have put the height of the bridge at 250 meters. 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 102 meters.
Although larger concrete viaducts and steel cantilever bridges were constructed before and after Gokteik, no other conventional box tower and girder type steel trestle has ever exceeded it in size except for the monstrous Lethbridge Viaduct in Alberta, Canada which is about the same in height but more than twice the length. The Joso bridge in the U.S. state of Washington, the Poughkeepsie bridge in the U.S. state of New York and the original Kinzua viaduct in the U.S. state of Pennsylvania are the only other traditional steel trestles that are equal in size to Gokteik.
Gokteik also had the tallest bridge piers in the world at the time of its completion at 97.5 meters. The current record is now held by France's Millau Viaduct at a record breaking height of 245 meters.
