Saint-Nazaire Bridge

The Saint-Nazaire Bridge extends 3,356 meters across the Loire Estuary, featuring a 404-meter main span and rising 68 meters above water level.

Construction of the bridge began in March 1972, with official opening in October 1975, marking the first cable-stayed structure across the Loire River.

The bridge connects the communities of Saint-Nazaire and Saint-Brevin-les-Pins, supporting regional development between the northern and southern banks of the Loire.

The three-lane roadway includes narrow cycling paths on both sides, with a speed limit of 70 kilometers per hour across the entire span.

Engineers implemented a variable lane system that adjusts traffic flow direction based on peak travel demands, allowing more efficient vehicle movement during busy periods.
