In **2024**, almost **half a billion tonnes** of goods moved across the EU this way, and the figure is rising. - **1:35** Most activity happens in three countries — the **Netherlands**, **Germany** and **Belgium** — whose canals join major ports such as **Rotterdam**, **Antwerp** and **Hamburg**. - **1:49** **France** has **8,500 km** of navigable waterways, the largest network of any European country, but it connects poorly to those neighbours. ### 2:08 Canal du Nord - **2:06** The one major link is the **Canal du Nord**, running from northern France down to the **Seine** basin ("yes, that Seine"). ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t0220.webp]] - **2:24** It took more than half a century to build — with the excuse of two World Wars, much of the fighting in this very region. - **2:39** After all that time it became obsolete quickly. Per the companion article, SCSNE technical director **Benoît Deleu** says it was started in the 1900s, completed in **1965**, and cannot take most of the European fleet. - **3:16** It is not suitable for big modern barges, and even those that fit have a tight squeeze. ### 3:14 Introducing SNEC - **3:16** France is "having another go" with a canal that does far more than replace its predecessor (Fred's "tour de force" / "crème de la crème" puns). ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t0320.webp]] - **3:33** The **Seine-Nord Europe Canal**: **107 km** long and **54 m** wide — much longer and wider than the Canal du Nord. - **3:49** It will take vessels over **seven times larger**, up to **4,500 tonnes**. - **3:49** Cost: **€7.3 billion**, half from **EU funding**; the rest from the **French government** and the regions and departments along the route, from **Oise** in the south to **Nord** in the north. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t0410.webp]] - **4:05** France has **13 metropolitan regions** and **96 departments**; Fred declines to go into arrondissements, cantons and communes. ### 4:35 The Benefits - **4:36** The waterway should boost trade, speed navigation and relieve other transport modes across Europe, not just France. - **4:51** That comes from its connection to neighbours via the **Seine-Escaut** river link. Deleu (in French; quote from article) describes it as a European large-gauge link through France and Belgium's **Flanders** and **Wallonia**. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t0500.webp]] - **5:13** That makes it a crucial part of the EU's **Trans-European Transport Network (TEN-T)** of railways, roads, ports and canals. - **5:27** Timeline: EU consent in **2013**; the **Société du Canal Seine-Nord Europe (SCSNE)** set up three years later; finances agreed three years after that; real work ready to begin in **2022**. - **5:42** Fred apologises for one more pun ("raison d'être") and moves on to the engineering. ### 6:06 The Locks - **6:12** It is more than digging a trench and filling it with water, as drone footage from **late 2025** might suggest. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t0610.webp]] - **6:27** **Seven locks** let boats handle varying terrain and water levels. Two will have drops of more than **25 m**, the **deepest ever built in Europe**; one shown is also **12.5 m** wide and **197 m** long. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t0640.webp]] - **6:43** Performance target: lockage time (filling or emptying) must not exceed **15 minutes** despite the size. - **6:59** To move water fast while limiting environmental impact, **cascading basins** beside each lock connect to the lock chamber through pumps and culverts so water can be recycled. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t0720.webp]] - **7:13** (Per the companion article, a **14 million m³** reservoir beside the canal will top up water in hotter months.) ### 7:39 Making Models - **7:41** Locks are designed with a mix of **digital technology** and detailed **physical scale models**, so complex parts can be optimised before they are built. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t0800.webp]] - **7:56** Example: the **perforated floor slab** between the lock chamber and the dissipation chamber below, which manages water flow. Models also test flow rates, measure forces with sensors, and trial the control valves. - **8:11** The virtual model is arguably more impressive: main contractor **Egis** needed hundreds of people to access and manage more than **a terabyte** of data. - **8:27** The answer was a **connected data environment** as the project's digital backbone, letting departments collaborate and visualise progress in real time. - **8:41** **Arnold Ledan** (Egis BIM manager) says the federated model makes the project easy to understand, and it is the first time they have had about **250 people** collaborating inside one model. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t0905.webp]] - **8:57** Using Bentley's **ProjectWise** as the common data environment enabled digital design reviews and easy clash detection. - **9:11** Egis has since added more Bentley tools: **MicroStation**, **OpenRoads**, and the **Bentley Infrastructure Cloud** for clash detection and issue tracking. - **9:42** Productivity up by over **40%**; model generation time down by over **60%** — freeing time to make the project beneficial rather than an eyesore. ### 9:51 Tourist Attraction? - **9:58** The locks will be very visible in the landscape and feats of engineering in their own right, so SCSNE plans to make them a **tourist magnet**. - **10:13** Fred argues everyone stops to watch a boat go through a lock — "Where's the ticket link?" ### 10:36 Crossings and Quays - **10:43** The route crosses territory full of existing transport links: **62 road and rail crossings** are in the design. - **10:43** Unlike the locks, which are only starting, several bridges are already complete — including one over an existing canal that will become part of Seine-Nord Europe. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t1100.webp]] - **10:59** Its metal frame was assembled on the south bank, set on temporary supports, then launched across the water with **cables, pulleys and winches**; it then docked on permanent supports to await **20-tonne** prefabricated concrete deck slabs delivered **by boat**. - **11:30** Using existing waterways is central to the strategy: **ten construction quays** move material off-road, cutting carbon emissions. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t1140.webp]] - **11:45** One quay beside the **Canal de la Sensée** (at Aubencheul-au-Bac, per the article) needed bank clearing and excavation, a watertight wall of **sheet piles** and concrete **capping beams**, then an asphalt surface so vehicles can carry material a short distance to the main sites. ### 12:11 Canal Viaduct - **12:16** The biggest section is yet to start: the **Pont-Canal de la Somme**, a viaduct carrying the waterway *over* existing infrastructure. - **12:16** At **1.3 km**, it will be the **longest canal viaduct in Europe**. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t1220.webp]] - **12:30** Deleu (in French; quote from article) gives three reasons for a canal bridge: let the **Somme** river flow freely, cross a protected natural area with the least environmental impact, and avoid building on compressible wetland ground. ### 13:21 Archeology and Ecology - **13:13** Reducing the canal's footprint across the **Somme Valley** makes sense for its rich ecology — and the valley is synonymous with the **Battle of the Somme**. - **13:29** About **100,000** soldiers who died on the **Western Front** of World War I are still missing. SCSNE works with the **Commonwealth War Graves Commission** on exploratory operations so remains are found in advance and buried in an expanded cemetery nearby. - **13:43** The project is recognised as **Europe's largest preventative archaeological initiative**, with finds back to the **Palaeolithic**. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t1350.webp]] - **13:58** **1,200 hectares** dedicated to biodiversity: wildlife crossings, around **60** sites turned into wetlands and ponds, and new trees. SCSNE says some species have already returned. ### 14:26 Conclusion - **14:28** Completion target **2032**, finally giving France proper access to the North European network and tying the wider continent more closely to the EU's **second-largest economy**. ![[images/The-7BN-Mega-Canal-That-Will-Reshape-Europe-t1440.webp]] - **14:46** Railways, airports and base tunnels get the headlines, but this could be a "**watershed moment**" for an under-appreciated kind of infrastructure. - **15:03** Bentley Systems sponsor message and subscribe call to action. ## Things mentioned ### Projects and waterways - Seine-Nord Europe Canal (107 km, 54 m wide, vessels up to 4,500 t, €7.3BN, 7 locks, target 2032) - Canal du Nord (completed 1965; too small for modern barges) - Seine-Escaut river link (France–Belgium large-gauge network) - Trans-European Transport Network (TEN-T) - Pont-Canal de la Somme (1.3 km, Europe's longest canal viaduct) - Canal de la Sensée (construction quay site) - River Seine and the Seine basin; River Somme ### Places - France: Oise, Nord, Somme Valley, Aubencheul-au-Bac (article) - Belgium (Flanders, Wallonia), the Netherlands, Germany - Ports of Rotterdam, Antwerp and Hamburg - Amsterdam, Bruges (canal examples) - Western Front / Battle of the Somme ### Engineering and construction - Deep locks (25 m+ drops; 12.5 m × 197 m chamber; 15-minute lockage) - Cascading water-saving basins, pumps and culverts; 14M m³ reservoir (article) - Physical scale models: perforated floor slab, dissipation chamber, sensors, valves - Bridge launch with cables, pulleys and winches; 20-tonne precast deck slabs delivered by boat - 62 road and rail crossings; 10 construction quays; sheet piles and capping beams ### Software and sponsor - Bentley Systems (sponsor): ProjectWise, MicroStation, OpenRoads, Bentley Infrastructure Cloud - BIM / connected data environment (1 TB+ data, ~250 users; +40% productivity, −60% modelling time) - Fred's book *MEGA BUILDS* (description promo) - *The World's Best Construction Podcast*; Get Construction Talking (description) ### Figures and dates - ~0.5 billion tonnes of EU inland-waterway freight in 2024 - France: 8,500 km of navigable waterways; 13 metropolitan regions, 96 departments - 2013 EU consent; SCSNE founded ~2016; funding agreed ~2019; works from 2022 - ~100,000 missing WWI soldiers; 1,200 ha for biodiversity; ~60 wetland and pond sites ### People and organisations - Fred Mills (host), Adam Savage (article author) - Benoît Deleu (SCSNE technical director) - Arnold Ledan (Egis BIM manager) - Société du Canal Seine-Nord Europe (SCSNE), Egis, Commonwealth War Graves Commission, European Union, French government ## Biographies ### Fred Mills Founder and on-camera host of **The B1M**, the YouTube channel and publisher covering construction and megaprojects. Presents this canal explainer from the studio with a string of self-aware French puns, and promotes Bentley Systems and his book *MEGA BUILDS*. ### Benoît Deleu Technical director at the **Société du Canal Seine-Nord Europe**. Interviewed in French; per the companion article he explains why the Canal du Nord can no longer serve most of Europe's fleet, how the Seine-Escaut link creates a large-gauge network through France, Flanders and Wallonia, and why the Somme crossing is a canal bridge (free river flow, protected habitat, compressible wetland soils). The auto captions render his name as "Ben Wallas." ### Arnold Ledan **BIM manager at Egis**, the canal's main contractor. Describes the federated 3D model that let about 250 people collaborate in one environment, built first on Bentley ProjectWise and later on MicroStation, OpenRoads and Bentley Infrastructure Cloud for clash detection and issue tracking. ### Société du Canal Seine-Nord Europe (SCSNE) The French public company set up about three years after the EU's 2013 consent to deliver the canal. It oversees construction, the archaeology programme with the Commonwealth War Graves Commission, and the 1,200-hectare biodiversity plan, and plans to make the giant locks a tourist attraction. ### Egis French engineering group serving as the main contractor. It manages more than a terabyte of project data through a connected data environment, credited with 40%-plus productivity gains and 60%-plus faster model generation.
