A bridge not too far: Safer, environmentally sound road travel for passengers in Sweden

ViaCon Sweden enables safer, more environmentally sound road travel, as the Swedish Transport Administration a new road at Scandinavian Mountains Airport

With the construction of the new commercial airport, Scandinavian Mountains Airport, to serve large ski resorts near Sälen in Sweden, Trafikverket, the Swedish Transport Administration, needed to build a new road to serve the increase in traffic.

The Challenge​

Bridge construction formed part of the road construction requirement, helping to shorten travel
distance for drivers. Design requirements included:

• Life load according to EN 1991

• A cover depth of 1.15 metres

• Backfilling parameters according to SDM with sub-base material

• 120 years’ durability

• Corrosion protection layers: zinc coating of thickness according to EN ISO 1461:2009 Fe/Zn 115, surface of the structure painted 100% on both sides with paint to thickness of 300 μm

The Solution

ViaCon Sweden met the challenge, providing UltraCor Special 38U, contributing to the successful construction of the bridge by August 2019. The resulting steel structure had the following measurements:

Span: 14.42 m
Rise: 4.13 m
Bottom length: 12.3 m
Top length: 12.3 m
Plate thickness: 9 mm
Steel grade: S420MC
