U Bein Bridge (Burmese: ဦးပိန် တံတား) is a crossing that spans the Taungthaman Lake near Amarapura in Myanmar. The 1.2-kilometre bridge was built around 1850 and is believed to be the oldest and longest teakwood bridge in the world. The bridge was built from wood reclaimed from the former royal palace in Inwa. It features 1,086 pillars that stretch out of the water, some of which have been replaced with concrete. Though the bridge largely remains intact, there are fears that an increasing number of the pillars are becoming dangerously decayed.
