Ny tramtunnel under Göta älv

The Lindholmen Connection project involves constructing a new tram tunnel in central Gothenburg, running partly underwater beneath the Göta River. The tunnel will connect the districts of Lindholmen and Linnéplatsen via an underground stop at Stigberget and pass under the city's large park, Slottsskogen. This tunnel aims to significantly improve public transport by reducing travel time between Lindholmen and Linnéplatsen from 25 to about six minutes, increasing capacity, and providing a more robust tram route with an additional river crossing.

Planlegging og tekniske utfordringer

Led by the land development department of the city of Gothenburg, the project is still in early stages, with COWI involved especially in planning and engineering tasks. Jonas Brunner, an urban and regional planning specialist at COWI, is responsible for preparing the railway plan, critical for organized and safe railway construction. The railway plan outlines land use along the tunnel route, track infrastructure, and includes an environmental impact assessment to address significant technical challenges, such as poor rock quality near Linnéplatsen and potential contamination risks during underwater construction.

Miljøhensyn og lokal planlegging

The tunnel construction includes complex environmental considerations due to riverbed dredging, which may release contaminants. Experts from COWI, including hydrogeologists, are working closely with the city and partner firms like AFRY and Arkitema to ensure the project meets environmental standards and integrates with urban development plans. A new local development plan for the route is also being prepared in coordination with the railway plan, which will be submitted to the Swedish Transport Administration for approval by the end of 2027.

Bærekraftig transport for vekst

The project is designed to support the city’s anticipated population growth of 100,000 people over the next decade by enhancing sustainable travel and reducing strain on existing transportation infrastructure. With this multidisciplinary collaboration and focus on sustainability, the Lindholmen Connection is expected to open in 2039 and contribute significantly to the reliability and capacity of Gothenburg’s public transit network.
