The remains of a Roman bridge were uncovered in Aegerten, about 20 miles northwest of Bern, Switzerland earlier this month, according to the Miami Herald. Experts found more than 300 oak piles well-preserved in waterlogged soil near the Thielle or Zihl River. There, the bridge once stood, connecting either side of the major waterway, outside of the gates the small Roman town Petinesca. The bridge was a key part of the Jura Transversal, a major Rome trade and transportation route between Roman military camps and settlements. Roman military structures were also previously identified in Aegerten approximately four decades ago.
