Pont de Châteauneuf-sur-Loire, Suspension bridge in Châteauneuf-sur-Loire, France.

The Pont de Châteauneuf-sur-Loire is a 276.50 m suspension bridge over the Loire between Châteauneuf-sur-Loire and Sigloy, carrying the D 11. Its deck is 7.00 m wide between the inner faces of the railings: a 5.50 m roadway and two 0.75 m pavements that continue past the piers. Four pairs of light blue lattice pylons stand in the river on stone piers, with black hanger cables and blue railings.

A royal ordinance of 23 September 1838 authorised the bridge, built by the Seguin company and opened in 1841. During testing in 1840 a stone block under a cable-supporting column gave way, collapsing the structure; only the last arch held. French military orders destroyed two spans in 1870, rebuilt by 1872, and the bridge was again wrecked in 1940 and reopened on 16 May 1946.

The bridge carries the D 11 road and is the only crossing of the Loire at Châteauneuf-sur-Loire, linking the town to the farming land and the village of Sigloy, 2.5 km to the south. The span lies within the Val de Loire area inscribed on the UNESCO World Heritage list. Look for the inscription "Café de la Loire" on the building beyond the right-bank end.

The bridge is accessible to both vehicles and pedestrians and crosses the river on a relatively level path. Be aware that it is an active traffic route, so care is needed when crossing on foot.

The main suspension cables are not continuous: they run only from the top of one pylon to the next, with 80 mm double cables and vertical hangers of 45 mm steel rods. Short pylons stand at each bank, tied to the anchor blocks by six anchor cables. The anchor blocks built in 1935 remain in place, 12 m long, 14 m wide and 5.80 m high.
