TECHNICAL TOURS

Oosterweel connection – Immersed tunnel

The technical tour of the Scheldt Tunnel of the Oosterweel Connection (immersed tunnel section) will give participants a unique opportunity to visit the site and learn more about the technical installations of the project. The structural works will already be completed, allowing the tour to focus on the installation and integration of the technical systems that are essential for the tunnel’s operation.

Oosterweel connection – Cut and Cover canal tunnels

This tunnel section is built using the cut-and-cover method along the Albert Canal, combining infrastructure integration with urban and environmental measures to limit surface disruption. During the technical tour in 2027 you can walk on some sections of the tunnel floor, 20 meters deep in the canals.

Oosterweel connection – Tunnels Oosterweel Interchange

Here you’ll get a unique look at the Oosterweel Interchange: a complex network of tunnels and on- and off-ramps that will connect the future Ring Road with the Port of Antwerp and the city. You’ll visit composite tunnels, interlocking tunnels, and stacked tunnels, where walls, floors, and roof slabs are being interlocked as construction is in full swing. Innovative formwork techniques, the use of concrete with PP fibers for fire resistance, and a complex logistics chain make the construction of this tunnel system possible.
Finally, you’ll get a glimpse inside the Scheldt Tunnel’s bicycle tunnel, where the finishing touches and tunnel engineering systems- with a special focus on safety systems-are visible in detail. An exceptional opportunity to experience the scale and logic of this transportation hub up close.

Pre-Metro in Antwerp

The Antwerp premetro network is a nearly 50-year-old underground tram system, which is undergoing major refurbishment because much of the infrastructure has significantly aged. Structural issues such as degraded tunnel lining, non-waterproof sections, and worn track beds require deep renovation rather than piecemeal repairs. In 2027, participants can expect to observe renovation works taking place nearby.

Underground lab in Mol/Dessel - High Activity Disposal Experimental Site (HADES)

The HADES Research Centre (High Activity Disposal Experimental Site) is a unique underground laboratory located in Mol, Belgium, at a depth of approximately 225 metres in the Boom Clay formation. Operated by EIG EURIDICE, a collaboration between the Belgian Nuclear Research Centre (SCK CEN) and the national radioactive waste agency ONDRAF/NIRAS, HADES serves as a long-term research facility for studying the safe disposal of high-level and long-lived radioactive waste. The laboratory allows scientists and engineers to investigate the geological, geotechnical, hydrogeological, and chemical behaviour of clay as a potential host rock, including its self-sealing properties, long-term stability, and interaction with engineered barriers.

Westerscheldetunnel (NL)

The Westerscheldetunnel is a key 6.6 km road tunnel in the Netherlands connecting Zeeuws-Vlaanderen with the rest of the country. It carries thousands of vehicles daily and is critical for regional mobility and freight movement. In early 2027, a significant repair project is planned on the east tube due to a crack in the concrete across several segments. Experts have confirmed after investigation that the tunnel is safe, but repairs will be necessary in the long term.

Beverentunnel - Tunnel Renovation

The Beverentunnel on Antwerp’s R2 is a strategic twin‑tube motorway tunnel for port and commuter traffic that has just been comprehensively renovated while remaining fully operational. It was upgraded in three phases to meet current European tunnel safety standards, with full renewal of the road surface, lighting, ventilation, fire‑suppression systems and escape routes, plus major sustainability improvements including a 750‑panel solar park and a water‑treatment installation handling around 3.6 million litres of groundwater per day. During the site visit, you will see the upgraded tunnel and its new technical installations, illustrating how a busy motorway tunnel can be future‑proofed without closing to traffic.

Please note that all scheduled technical tours are subject to change or cancellation based on site availability, safety requirements, and project progress. While every effort will be made to adhere to the published itinerary, the ITA WTC2027 Organising Committee reserves the right to modify tour destinations, schedules, or logistics to ensure the best possible experience and compliance with active construction site regulations.
