Tunnels: Canal des Ardennes

The canal des Ardennes branches off from the canalised river Meuse (formerly the ‘northern branch of the canal de l’Est’) at Pont-à-Bar, a short distance upstream from Charleville-Mézières. After crossing the watershed between the rivers Meuse and Aisne it drops down the Aisne valley to connect with the canal latéral à l’Aisne at Vieux-lès-Asfeld. The distance from the Meuse to the canal latéral à l’Aisne is 88km. Originally it was 5.5 km longer, entering the Aisne further downstream, but this section was bypassed by the lateral canal in 1841. A 12km long branch leads from Semuy to the small town of Vouziers, further up the Aisne valley. Officially the canal is divided into two lengths, with distances counted separately on the watershed link, from Pont-à-Bar to Semuy, and on the canal following the Aisne valley, from Vouziers to Vieux-lès-Asfeld.

St-Aignan

The St-Aignan tunnel on the canal des Ardennes can be found at the northern end of the canal summit near the village of St-Aignan in Ardennes (08). It is controlled by traffic lights that are also connected to a pair of locks on the northern side as the canal and tunnel aren't wide enough at that point for two boats to pass. It has a towpath on both sides but only one side is open to the public.
