Stockholmsmässan – venue for World Tunnel Congress 2025

From 9 to 15 May 2025, Stockholmsmässan is the platform for the future of underground infrastructure. More than three thousand experts from around eighty countries will gather at this world-leading congress and exhibition on tunnelling and underground construction.

“We are immensely proud to welcome the World Tunnel Congress 2025 to Stockholmsmässan. Our venue is designed to facilitate meetings where innovation, knowledge sharing, and international collaboration are at the forefront. The congress is important for the industry but also a testament to Stockholm’s appeal as a destination for scientific events,” says Anna-Karin Werner, Head of Congresses and Guest Events at Stockholmsmässan.

The World Tunnel Congress (WTC) is an annual international congress and exhibition. For the first time, Sweden will host the event, which is being organised by the Swedish Rock Engineering Association with support from the International Tunnelling and Underground Space Association (ITA). The practical arrangements are handled by Meetagain, a professional conference organiser (PCO) based in Stockholm. Stockholm Business Region played a key role during the initial planning phase in bringing WTC 2025 to the city.

“The World Tunnel Congress is a strategically important event that reinforces Stockholm’s position as a leading city for sustainable infrastructure and technological innovation. By bringing the world’s experts together here, we are showing that Stockholm is a place where future solutions are shaped – while also boosting the city’s international visibility and economic growth,” says Karin Mäntymäki, Head of International Market Development at Stockholm Business Region.

Focus on Sustainability and Swedish Engineering Excellence
The theme of WTC 2025 is “Tunnelling into a Sustainable Future”, highlighting how underground solutions can contribute to sustainable cities and infrastructure. Sweden will be showcased as a pioneer in technical innovation – from historic trailblazers like Alfred Nobel to today’s world-leading companies and projects in electrification, autonomous systems, and climate-smart solutions.

The congress will feature nearly 600 presentations, technical site visits including Förbifart Stockholm and the new Stockholm Metro, and a comprehensive exhibition with over 160 exhibitors.
