Saphan Khom (Saphan Hin)
Saphan, a Thai word meaning bridge, is a historic site with roots in Khmer history. The structure is believed to be an ancient bridge linking SakonNakhon to the countryside, as the area was once a swamp, often used by the Khmer people. The present bridge is made of laterite and replaced a previous bridge that had been removed to make way for roads.The historic site is located on Nittayo Road, at Km. 161 off Highway No. 22. It is located just prior entering SakonNakhon town on SakonNakhon-UdonThani Road.
