After 9 months of work, the secondary lock of La Cave, at Bois-le-Roi (Seine-et-Marne) on the Upstream Seine, has been completely renovated and put back into service on 30 January 2023.
The re-opening of this secondary lock, which had been out of service since the early 2000s, then re-commissioned in 2019, means that there are now two operational locks on La Cave site. This will thus contribute to improving the conditions for river traffic on this very busy wide-gauge route (11,000 freight boat passages per year, i.e. an average of 6 million tonnes of goods transported).
This operation carried out by Voies navigables de France (a member of the Seine-Scheldt EEIG), represented an investment of €7 million (including tax) and was co-financed by the European Union (as part of the Connecting Europe Facility – CEF) and the Île-de-France Region.
This re-commissioning comes after those of the other secondary locks on the Upper Seine, upstream of Paris: Coudray (Essonne) in 2020 and Vives-Eaux (Seine-et-Marne) in 2022. Work on the fourth secondary lock, at Champagne (Seine-et-Marne), will begin in April 2023.
