Oosterweel milestone: a final glimpse before the tunnel elements disappear underwater
After two years of intense construction, the eight gigantic elements of the Scheldt Tunnel are ready for their next journey. At the construction dock in Zeebrugge, Belgium, Lantis and TM COTU, including DEME, have started flooding the basin with no less than 800,000 m³ of water, the equivalent of 320 Olympic swimming pools.
Once the dock is full, the tunnel elements, each larger than a football field and weighing up to 60,000 tonnes, will disappear beneath the surface, marking a symbolic moment in this impressive construction project.
Soon, these concrete giants will begin their 100+ km journey towards Antwerp, where they will be immersed to form the Scheldt Tunnel, a key link in the completion of the Antwerp Ring. The first element is scheduled to begin its 30-hour journey in May.
Well done to the entire construction team in Zeebrugge!
