The Don Khon Railway Bridge was a key part of the Don Det–Don Khon railway, a 7-kilometre narrow-gauge portage railway built in 1893 during French colonial rule in Laos. It connected the islands of Don Khon and Don Det within the Si Phan Don archipelago, enabling vessels and freight to bypass the impassable Khone Phapheng Falls on the Mekong River. Initially constructed with a temporary track, the railway was later made permanent and operated with a wood-burning steam locomotive named Paul Doumer. The railway facilitated transport of passengers and goods along the Mekong until its closure around 1940. This railway was the only operational railway in Laos until 2009, making the Don Khon Railway Bridge a unique relic of colonial engineering and regional transport history. Today, the bridge and remnants of the railway attract visitors interested in Laos' colonial past and the Mekong River's navigation challenges.

History

1893

Constructed in 1893 by the French colonial administration, the Don Det–Don Khon railway was designed to circumvent the Khone Phapheng Falls, a major obstacle to navigation on the Mekong River.

Initially using temporary tracks and manual labor, it soon employed a steam locomotive to transport dismantled vessels and cargo across Don Khon and Don Det islands.

The railway was extended to Don Det in the 1910s to improve connectivity.

1940

It operated until around 1940, after which it was abandoned due to changing transport needs and the impact of World War II.

It remained the only railway in Laos until the early 21st century.
