Voies Navigables de France has awarded BYTPRF the contract for the extension of the lock at Quesnoy sur Deûle. The project consists of bringing the lock up to standard by lengthening the downstream head, including the new mitre gate. The construction of a pumping station, improvement of the fish passage and the rehabilitation of the three existing buildings are also planned.

Currently 110 metres long, the extension to 144 metres will ultimately enable large convoys (135 metres) to go through, at a strategic point between the future Seine-North Canal and the countries of Northern Europe. This modernisation work contributes to the development of transport modes that are complementary to road transport.

Congratulations to the teams for securing this new contract!

The consortium: Bouygues Travaux Publics Régions France (leader), Baudin Châteauneuf, Baudin Châteauneuf Métal Nord

In 2018, Bouygues Travaux Publics Régions France delivered the renovated and upgraded Don lock. Located on the Deûle canal, south-west of Lille, the lock allows maritime traffic to navigate between the port of Dunkirk and the capital of Flanders, ensuring the transit of 5.3 million tonnes of goods each year.

Since 2020, BYTP and BYTPRF teams have been working on the almost complete reconstruction of the Méricourt locks, to guarantee their reliable operation, as well as the necessary adaptation to current river traffic.
