23km

highway

in the heart of Norway

Design and construction of 23 kilometres of four-lane highway, of which 8 km will be underground, with four tunnels of between 1 and 4 kilometres long.

The route, which also includes eight bridges, will be partially completed over the old road, with the exception of the tunnels, which will run parallel to the current ones. Thanks to this new infrastructure, the road will go from two to four lanes, thus facilitating travel in the northern part of Trøndelag County.

 

The route, which includes eight bridges, will largely follow the old road, with the exception of the tunnels, which will run parallel to the existing ones. This new infrastructure aims to improve connectivity in the northern part of Trøndelag County, central Norway.

The work, which will begin in mid-2020, will be completed in 2024. Until its re-opening, ACCIONA Construction will also be responsible for managing traffic and constructing temporary alternatives to maintain the flow of vehicles between the two cities.

The Norwegian state-owned road planning, construction, operation and maintenance company Nye Veier has chosen ACCIONA to design and construct this new project. In addition, until its re-opening, it will also be responsible for managing traffic and constructing temporary alternatives to maintain the flow of vehicles between the two cities.

 The new construction section has the following characteristics:

  • 23 km of 4 lanes compared to the two existing lanes (2+2)
  • 8 bridges (240 m, 290 m AND 6 adding 300 m in length)
  • 4 tunnels, 8.3 km in total (1.7, 1.8, 0.9 and 3.9 km)

The recent awarding of the E6 Ranheim-Værnes highway strengthens ACCIONA Construction's presence in Norway. At present, it is working on designing and constructing two twin 18.5 km tunnels within the Follo Line project, which, once completed, will be the longest railway tunnels in Scandinavia.

GENERAL INFORMATION

  • Location: Trondheim, Norway.
  • Type of contract: Design and Construction.
  • Infrastructure: 23 km of highway which includes four tunnels of between 1 and 4 kilometres.
  • Construction end year: 2024.

KEY ASPECTS

Since the project was awarded in 2018, ACCIONA has completed basic design work with Nye Veier under the client-contractor association model being implemented in the Norwegian public works market. The company hired Rambøll and Leonhard Nilsen & Sønner AS as subcontractors for the project.

Basic design work included reducing the risk of unforeseen circumstances. It also optimised the road design to improve safety and traffic flow during the construction phase.

According to current zoning plans, the route comprises approximately 15 km of open road, including bridges and approximately 8 km of tunnels.

The route includes 4 double tunnels:

  • Være tunnel (1,700 m), constructing one new one and restoring another.
  • Stavsjøfjell tunnel (1,800 m), constructing one new one and restoring another.
  • Hommelvik tunnel (900 m), constructing two new ones.
  • Helltunnelen (3,900 m), constructing one new one and restoring another.

The route includes 8 bridges:

  • Hommelvik Bridge (240 m), 3,158 m2.
  • Sandfærhus Bridge (290 m), 3,615 m2.
  • Remaining bridges: 6 bridges with a total of 300 metres.
