This bridge is the best-known historical landmark in Kanchanaburi. It was erected through the forced labor of British, Dutch, and American prisoners of war during WWII. The bridge was part of the Thai-Burmese "Death Railway," so named because of the scores of men who died during construction. Japanese forces oversaw the project, as the railway would have helped bring supplies to their troops who were fighting the British in neighboring Burma. Today, you can ride across the bridge, sections of which are from the original structure.
