Cize-Bolozon viaduct crossing the Ain gorge, France

Cize-Bolozon viaduct, France

Imagine a bridge that connects more than just two sides of a river. Nestled in the Ain department, the Cize-Bolozon Viaduct—featured in today's image—has accomplished this feat for over 70 years. Built in 1950 to replace a structure destroyed during World War II, it has watched over the valley with understated elegance ever since.

What makes it truly unique? It combines two functions on two stacked levels: trains travel above, cars below. With its reinforced concrete arches and a length of 273 metres, it overlooks the Ain Gorges at a height of over 60 metres. But this viaduct is not just a technical feat. It is also a place steeped in history and poetry. At dawn, mist rises between its pillars, creating an almost surreal spectacle. Whether you are passionate about architecture, history or simply curious, this bridge is well worth the detour. It doesn't just connect two dots: it weaves a link between eras.
