On a bicycle tour from Hoi An, this was one of four bridges, two bamboo, two of wood that we crossed.  This one was owned by three families and the Bridge Man sleepy in a hammock,  waited at the end for the toll. The bridge only slightly more sturdy than its shadow, seemed like an invitation for me and my bicycle to fall into the river, so I wheeled my bike across. At the slower pace one gets to appreciate the aging process for bamboo.
