Viaduc ferroviaire de Sully-sur-Loire

The Sully-sur-Loire railway viaduct is a metal bridge that spans 410 meters across the Loire River using multiple arches to support its structure. The construction connects both banks of the river with its distinctive industrial design.

Built in 1859, this structure represents the railway expansion during France's Second Empire and shows the era's industrial progress. It stands as a surviving example of mid-19th-century engineering achievement.

The viaduct has been repurposed as part of the Loire cycling route, connecting travelers with the Renaissance castle and local communities. This transformation shows how industrial structures become gathering spaces for visitors and residents alike.

Walking across the viaduct provides views of the river and surroundings, though the metal surface can get warm in direct sunlight. Wear comfortable shoes and stay aware of cyclists sharing the path.

The bridge crosses the Loire at its widest point in the region, offering a rare view where the river, castle, and landscape align in one perspective. Few visitors realize the structure carries cyclists and pedestrians rather than the trains that once ran here.
