Tangenvika railway bridge

See how Norway's longest railway bridge is being built

The Tangenvika railway bridge is currently being built over Lake Mjøsa. Welding of the enormous pile tubes for the foundation of the bridge is being done by Nordic Steel.

- Keller Geoteknikk AS has chosen Nordic Steel as its supplier to weld steel piling pipes for the Tangenvika project. The pipes are up to 1.4 meters in diameter and 85 meters long. "The welding must follow strict execution procedures and tolerances, as the pipes are components of the bridge foundation," explains Wojciech Szczepinski, project manager at Keller.

Welding coordinator at Nordic Steel, John-Christian Bruntveit, follows production in Tangenvika closely.

Very high level of welding technology

Since August 2023, Nordic Steel has had a base for welding technical personnel and performed complex and specialized welding at the construction site in Tangenvika.

- "We've optimized a production hall in Tangenvika for advanced, robotic welding of pile pipes. Here we use an automated welding process that ensures quality and accuracy," says Torjus Ulsaker, Head of Construction at Nordic Steel.

John-Christian Bruntveit is one of Nordic Steel's welding coordinators, and has worked permanently at the Tangenvika plant for the past year. He emphasizes the close follow-up on welding: "All welding is checked and followed up by our welding engineers.

Double track on the railway

The construction of a railway bridge over Lake Mjøsa is a complex and exciting construction project that will have the least possible impact on the environment in and around Lake Mjøsa.

When the project is completed, it will be a major boost for climate-friendly travel and freight traffic between Oslo and Hamar.

- We at Keller are pleased that we can work on this project with highly experienced and competent employees from Nordic Steel, and that the work will be delivered to the required standards," says Wojciech Szczepinski.
