Canal de l'Oise à l'Aisne
Information about the 48km long Canal de l’Oise à l’Aisne
The Canal de l’Oise à l’Aisne, opened to navigation in 1890, forms an important link between the Canal latéral à l’Oise at Abbécourt basin (PK 3) and the Canal latéral à l’Aisne at Bourg-et-Comin (PK 38). This 48km junction canal still carries regular commercial traffic (up to 20 barges a day), but is also on one of the main routes used by boats heading south from Calais, Dunkerque or Belgium. The route is regularly used by commercial traffic, which as always, takes priority at the locks, and at the tunnel.
There are short aqueducts at each end of the canal, over the rivers Oise and Aisne.
The summit level between the two valleys, at an altitude of 66m, includes a 2365m long tunnel at Braye-en-Laonnois. The tunnel’s width at water level is 6.50m, and the free headroom at least 3.50m. All vessels proceed through the tunnel under their own power, respecting the lights at each entrance. There may be delays of up to one hour.
History – Part of the Freycinet plan, this link canal was one of the last to be built in France. It was opened in 1890, with locks 40.50 by 6 m and a depth of 2.20m. These dimensions still apply today. The canal provides a short cut between Champagne and the Canal de Saint-Quentin, crossing the Oise on a fine aqueduct.
Key Waterway Dimensions
- Max Beam: 6m
- Max Height: 3.50m
- Max Draught: 2m
Navigation The canal is very attractive, almost entirely rural, deep in the countryside away from towns and even villages. It ascends slowly to a plateau, then through the Braye-en-Laonnois tunnel and then fairly quickly descends to Bourg-et-Comin. Traffic may be relatively dense until at least March 2017, while the river Aisne remains closed following partial failure of the weir at Vic-sur-Aisne.
Locks – There are 13 locks, of which 9 climb 24.96m from the Oise to the summit level, while 4 drop the 14.25m difference in level to the Aisne. They are of improved Freycinet dimensions, 40.50 by 6.00m.
Draught – The maximum authorised draught is 2.00m.
Headroom – The fixed bridges offer a headroom of not less than 3.50m.
Towpath – There is a towpath throughout.
