The Pont Charles-Albert was named after the King of Sardinia who commissioned its construction to link Annecy and Geneva.
The Pont Caquot was named after its engineer, Albert Caquot, a pioneer in concrete construction.
The 1839 bridge was once considered one of the most significant engineering achievements in the Alps due to its 192-meter span.
The site acts as a geological boundary where the Usses River has carved through layers of Urgonian limestone.
During the mid-19th century, the toll-based crossing was a critical node for trade between France and the Italian territories.
Le site des Ponts de la Caille features two distinct bridges spanning the Usses River canyon in Haute-Savoie, France. The older structure, Pont Charles-Albert, is a suspension bridge completed in 1839, currently preserved for pedestrian use. The newer structure, Pont Caquot, is a concrete arch bridge finished in 1928 that serves modern vehicle traffic. The canyon floor sits approximately 147 meters below the deck of the newer bridge. The site marks the historic border between the former Duchy of Savoy and the Kingdom of France. Visitors can walk across the pedestrian bridge to observe the architectural transition between 19th-century suspension technology and 20th-century concrete engineering. The surrounding topography is characterized by steep limestone cliffs and dense woodland. Access to the viewpoints is provided by pathways near the bridge abutments.

Wear sturdy walking shoes to navigate the gravel paths leading to the canyon viewpoints.
Visit during clear weather, as fog often settles in the deep Usses canyon, obscuring the views of the river below.
Use the pedestrian-only older bridge to access the best vantage points of the concrete arch.
Do not attempt to walk along the shoulder of the Pont Caquot, which is restricted to high-speed vehicle traffic.
Respect the historic structures by not climbing on the railings or stone supports.
