Speaking about “Sangkhlaburi district”, the first things that come to mind should definitely be a picture of a wooden bridge stretching across the river. The bridge is embraced by verdant mountain ranges, surrounded by plants of diverse species, and covered by a thin layer of fog. The dazzling bridge that reflects the charm of local people’s way of life is named Uttamanusorn Bridge or commonly known as Mon Bridge. Formerly, it ranked Thailand’s longest wooden bridge with the length of 850 meters and the world’s second longest wooden bridge . Uttamanusorn Bridge links the two banks of Songaria River at Nong Lu subdistrict, Sangkhlaburi district, Kanchanaburi province.This bridge was built under the initiation of Luang Phor Uttama, the abbot of Wang Wiwekaram temple. The construction was completed by labours of Mon people. The bridge was considered the route of an international friendship between Thais and Mons because it links together Sangkhlaburi district to the Mon community on the other side of the bank. Additionally, it became one of the well-known tourist attractions in Kanchanaburi.
