Archaeological teams in Switzerland have uncovered the remains of a remarkable Roman wooden bridge that served as a crucial transportation link for over four centuries. The discovery in Aegerten, near Biel, reveals sophisticated engineering techniques that highlight the Romans’ mastery of infrastructure development across their vast empire.
More than 300 well-preserved oak piles emerged during construction work, providing archaeologists with a treasure trove of information about Roman engineering capabilities. The wooden posts, protected by groundwater conditions, offer unprecedented insights into bridge construction techniques used throughout the Roman Empire.
