Viaduc de Bandol, Railway bridge in Bandol, France

The viaduc de Bandol is a masonry arch railway bridge at Bandol in the Var, southern France. It carries the Marseille-Saint-Charles to Ventimiglia line over the Grand Vallat. Its pale stone structure shows a row of round-headed arches on rectangular piers, with a thicker buttressed pier at one end, above a curved road that passes beneath it.

The viaduct carries the Marseille-Saint-Charles to Ventimiglia railway line across the Grand Vallat. The line was built through Bandol in the 19th century, and the masonry arch structure was erected as part of that coastal route. The bridge remains in railway use today.

The viaduct carries the Marseille–Ventimiglia railway over the Grand Vallat, so trains crossing it are part of daily life in Bandol. Its ten round-headed stone arches and pale parapet, seen from the shore, make it a recognisable feature of the coastal townscape.

The viaduct crosses the Grand Vallat just east of Bandol station on the Marseille–Ventimiglia line, so it is reached on foot from the town centre. The arches stand at the water's edge, with a stone-lined shore beneath them; the roadway passes under the span. Trains still run across it, so keep off the track bed.

The viaduct carries the Marseille–Ventimiglia railway line across the Grand Vallat, a stream that gives the structure its reason for existing. Look for the thicker, buttressed pier at one end, visible in photographs of the bridge, which braces the masonry against the valley side.
