On the way to Nantua (France)

Crossing the Rhône river to Pougny

Fort l'Ecluse - la porte du Pays de Gex

A great fortification to be visited again

L'Autoroute des Titans (A40 motorway) - just outside Nantua

There are no fewer than 8 viaducts over a 20-kilometer stretch

I'll be back on this route not least to cross this viaduct
