U Bein Bridge is a crossing that spans the Taungthaman Lake near Amarapura in Myanmar. The 1.2-kilometre (0.75 mi) bridge was built around 1850 and is believed to be the oldest and longest teakwood bridge in the world. It is used as an important passageway for the local people and has also become a tourist attraction and, therefore, a significant source of income for souvenir sellers.
