Turnkey contractor ACCIONA is design and constructing of 23 kilometres of four-lane highway in collaboration with Norwegian state-owned Nye Veier
Design and construction of a 23-kilometer four-lane highway
The project involved the design and construction of a 23-kilometer four-lane highway along the existing E6 route. It also included the construction of three tunnels parallel to the current ones. The project features eight bridges and three grade-separated interchanges. This new infrastructure will expand the road from two to four lanes, improving mobility in the northern part of Trøndelag county.
Construction began in 2020 and was initially planned for completion in 2027. Until the reopening, ACCIONA was also responsible for traffic management and the construction of temporary and alternative routes to maintain traffic flow between Ranheim and Værnes.
ACCIONA completed its work in 2023.
GENERAL INFORMATION
- Location: Trøndelag, Norway
- Contract type: Design and construction
- Project completion: 2027
Since the award of the project in 2018, ACCIONA has carried out basic design work with Nye Veier under the client-contractor partnership model being implemented in the Norwegian public works market. The company engaged Rambøll and Leonhard Nilsen & Sønner AS as subcontractors for the project.
The basic design work included how to reduce the risk of unforeseen circumstances. It also optimised the road design to improve safety and traffic flow during the construction phase.
According to the 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), one newly constructed and one rehabilitated.
- Stavsjøfjell Tunnel (1,800 m), one newly constructed and one rehabilitated.
- Hommelvik Tunnel (900 m), two new constructions.
- Helltunnelen (3,900 m), one newly built and one refurbished.
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.

On behalf of Nye Veier, we will build a 23 km new four-lane motorway from Ranheim to Værnes. Here is an overview of the start of construction on the various projects.
The entire stretch between Ranheim and the airport at Værnes is scheduled for completion in 2025. New Roads will open on the road between Trondheim and Hommelvik at the end of 2024. The road between Trondheim and Reitan, at today's exit to Storsand, is scheduled to open in early 2024.
ACCIONA is making an efford to minimize the enironmental impact generated by the E6 Ranheim-Værnes project by impleting measures and always following profesional advice.
Here are some examples of how we constantly work to safeguard nature and the environment in the local area:
Fish and mussels from the Rivers Homla and Høybybekken have been removed from the area affected by the project, and placed upstreams in a safer area.
We will create an artificial pond to create a suitable habitat for frogs upstreams in Høybybekken.
When finalized, the area of Høybydalen will be improved for salmon and trouts migration with the new circuit.
All areas are carefully studied to minimize the impact over the fauna, for example, respecting nesting areas or bats corridors.
Protected species: ACCIONA helped to mark where a special orchid bloomed which has not been seen since 1975.
We monitor the noise generated by the project placing noise monitoring stations and, when needed, noise barriers are set up.
We have also implemented a monitoring system to keep control on the water quality of the rivers to identify any possible effect over them
All process water from tunnel construction is treated in the 4 Water treatment plants that Acciona has in the pro
ACCIONA aims to build the new E6 as gently as possible. We do what we can to ensure that people and the environment along the road are exposed to as little inconvenience and strain as possible.
We try as best we can to set up the work so that the risk of damage is as small as possible. However, we cannot guarantee that damage will not occur. Experience from previous projects shows that some injuries can occur even if we have taken our precautions.
If someone still thinks that we have not behaved gently enough, just get in touch with us, and we will come and assess the relationship.
Damage to buildings can occur because of vibrations or rubble after blasting. We therefore often put out vibration meters that monitor the level of the vibrations during blasting. Most of the blasts is to open new barrels in the three tunnels.
For more information, you can consult the Blast notifications.
We recommend that you report the damage to your insurance company. It is important that this is done quickly. Insurance companies usually require that claims be reported within a certain time after the damage is discovered. The insurance company would like to have a claim rate prepared, assess the claim and the cause. In the event of payment after damage, the company will consider whether they will file a recourse claim against the Nye Veier/Acciona.
If you discover damage that you believe is caused by our construction activity, e-mail us or a send a letter to ACCIONA xxxxxx. Give a brief description of the damage and when it was discovered. Feel free to document with photos. We will contact you and make an initial assessment of the damage. In the event of damage to homes that may be related to blasting work, we will investigate whether the home has been mapped earlier and what may have been registered by previous damage. We will also examine the vibration measurements and any blasting report.
