Freyssinet Test Arch

The Freyssinet Test Arch is a 50-meter concrete span in Moulins that rises just 2 meters, supported by steel cables anchored within solid concrete abutments. The structure displays a flat, elegant profile designed to test how the material behaves under tension.

Eugène Freyssinet built this experimental structure in 1909 to study how concrete responds to tension forces. The successful tests here led him to design and construct three major bridges spanning the Allier River.

The arch represents a major advancement in civil engineering, leading to the development of prestressed concrete techniques used worldwide in construction.

This structure sits on private property along rue de Lyon and is partly buried in the ground, which limits visitor access. Check ahead about viewing possibilities before planning a visit.

This structure gained historical monument status in 2021, recognizing its pioneering role in concrete innovation. This official designation highlights how groundbreaking engineering work itself becomes worthy of preservation.
