Driving sustainable urban mobility in Gothenburg

"Vasastan is one of the most technically demanding infrastructure projects currently under construction in Sweden”, explains project manager Rickard Karlzén. “We are building extensive underground infrastructure in the heart of Gothenburg, where every step requires careful planning, advanced tunnelling expertise and close coordination with stakeholders. What makes me particularly proud is how our team consistently manages this complexity while maintaining a strong focus on safety, quality and production progress."

In central Gothenburg, Implenia is constructing key parts of the Vasastan project on behalf of the Swedish Transport Administration (Trafikverket). The project forms part of West Link (Västlänken), a major infrastructure investment that will improve regional connectivity and create more sustainable urban mobility for future generations.
A technically demanding project
The work includes the construction of a double-track railway tunnel, service and rescue tunnels, ventilation facilities and station-related underground infrastructure. Much of the construction takes place deep within the bedrock beneath a dense urban environment, requiring advanced tunnelling expertise, careful planning and close collaboration with stakeholders.

Visitors to the project are often struck by both the scale of the underground work and the engineering precision required to deliver them safely and efficiently. The progress achieved so far reflects the commitment, expertise and teamwork of the project team working beneath one of Sweden's busiest city centres.
Creating long-term value
The Vasastan project highlights Implenia's strength in delivering technically demanding infrastructure projects in complex urban settings. By combining engineering excellence, innovative construction methods and a strong focus on safety and sustainability, the project is creating long-term value for both the city of Gothenburg and its residents.
As construction progresses, the project team continues to work towards important milestones that will help transform public transport in western Sweden and support more sustainable travel for decades to come.
The Vasastan project

The Vasastan project is part of the Haga section of the West Link (Västlänken) railway expansion in Gothenburg, Sweden. It involves constructing a large underground station area, including a railway tunnel, a parallel rescue and service tunnel, and ventilation and fire-gas tunnels, with the overall Haga section comprising around 1.7 km of tunnels and a new underground station.
