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 next to U Bein Bridge in Burma. Uttamanusorn Bridge links the two banks of Songaria River at Nong Lu subdistrict, Sangkhlaburi district, Kanchanaburi province.
