Nantua - A40 viaduc de Nantua-Neyrolles
🇫🇷 Auvergne-Rhône-Alpes · France
This camera watches the A40 motorway where it crosses the Nantua-Neyrolles viaduct in the Ain department. It is a traffic camera, so it is useful for seeing how the road looks before you set off. The page also shows local time and the weather for Nantua.
Nantua is a small town on the edge of Lake Nantua, a glacial lake in the Jura foothills of eastern France. The surroundings are wooded limestone hills and gorges, and the area sits in the Auvergne-Rhône-Alpes region between Lyon and the Swiss border. The lake and the old town are the main local draws, and the A40 has long been the route that links this valley to the rest of the country.
The camera is aimed at the motorway and viaduct, so it is best used for checking traffic flow, queues and the state of the carriageway. Conditions change most with the time of day and the season: weekend afternoons and holiday departures tend to be busiest, and snow or fog in winter can affect visibility on this higher stretch. Compare the live view with the weather block below before you travel.
Nantua has a temperate, continental-influenced climate with cold, sometimes snowy winters and mild summers. The Jura hills make mornings and evenings cool even in warm months. Nearby cameras on the same road, including the Chamoise tunnel and the Saint-Martin-du-Frêne stretch near Oyonnax, let you check the route in both directions before you leave.
