Norconsult is the design consultant in this project and has been responsible for all design work related to the bridge structure. In addition, Norconsult has overseen the construction phase.
The concept from the earlier stages was retained but optimized through adjustments of span lengths and axis placement. Foundation work in Lake Mjøsa, involving 80-meter-long steel pipe piles, is a complex operation. By increasing the span lengths, the number of pile groups was reduced, resulting in technical, economic, and environmental benefits.
The bridge is being constructed using MSS (Movable Scaffolding System), which are suitable for spans up to 70 meters. The optimized solution includes 16 axes, compared to 23 in the original plan. The steel pipe piles are unreinforced, with the steel utilized structurally in accordance with the composite standard NS-EN 1994.
The design process is fully model-based, with all information and construction documentation digitally integrated into discipline-specific models. Key design choices – including fewer foundations and piles, unreinforced steel pipe piles, and a shorter bridge – have led to a substantial reduction in greenhouse gas emissions, saving as much as 9,900 tons of CO₂ equivalents.
As of August 2025, the Tangenvika Railway Bridge is under construction. The substructure has been completed in axes 10 through 16, as well as in axis 2. The superstructure has been established in axes 13 through 16, and the work is progressing well.
