Fosenbru Conference 2020

We have envisaged that we will now arrange Fosenbru conferences, either every two years, depending on how much new material it will be. The first of its kind was scheduled for June 3 or 4, 2020 at the Ørland Cultural Center in Brekstad. It is now clear that it must be postponed until such events can be held.

We have so far been in a phase of basic investigations, while we are now into a new phases in which we are preparing projects. We want people at Fosen and others to be able to keep up with this work, as well as the more general developments in areas that are important to the projects.

It will be a one-day conference, and the program that was prepared consisted of, among other things:

The forecast calculations Fosen 2060
Population, jobs and traffic ahead by the year 2060

Otherwise, we plan input from various stakeholders, with subsequent debate and input from the auditorium. We will return to this when a new date is clarified.

Investigation program for business

Soon we will invite business and industry to collaborate on an investigation program for business and industry at Fosen. We envision that subcommittees will look at aquaculture, agriculture, real estate, industry, trade and service, and the business community otherwise.

The themes will be how new infrastructure can affect recruitment and access to labor, productivity, value creation, growth, and Fosens and Trøndelag’s attractiveness as a working region.

The Fosenbru projects in the short and long term

We are now seeing the end of a few years with several basic investigations, and as mentioned above, we are now entering new phases where we are preparing projects. A significant part of this will be planning and impact analysis in accordance with the Planning and Building Act for connections and crossing the Stjørnfjord.

Other topics will include environmental data for waves, wind and electricity, design basis for the cruise, financing analysis, contracting and implementation strategies, etc.
We will come back on this one.

The overview study for crossing the Stjørnfjord is available

The consulting company Rambøll has now completed the overview study for crossing the Stjørnfjord, which for Fosenbrua AS is a very important step forward. The study has been sent to the respective municipalities as a basis for meetings with Fosenbrua AS on further follow-up.

=> Kryssing av Stjørnfjorden – Bru eller tunnel (Rambøll jan 2019) (Norwegian)

As is known, the bottom conditions and the mountain course in the Stjørnfjord were mapped with acoustics / light seismic in the summer of 2018, and with a requirement for minimum mountain coverage of 50 meters, an underwater tunnel would have to fall to around 300 m below the sea (muh). Compared to other submarine tunnels, this is relatively deep. The world’s deepest subsea tunnel today is Fv.653 Eiksund tunnel between Volda and Hareid at -287 m, while Rv.13 Ryfast connection between Stavanger and Ryfylke will be the deepest with -291m when it opens in 2019.

Fv. 714 Heat tunnel -264m
Fv. 714 Frøya tunnel -164m

With a depth of 300 meters, Rambøll’s review shows that it will have a length of about 14 km to satisfy the current requirement of a maximum increase of 5%. The traffic analyzes carried out indicate that the connection will have a traffic of over 2,600 vehicles in average daily traffic (ATT) already at the opening, and 3200 bits. AED with new road between Fevåg and Rissa.

The requirements for submarine tunnels have intensified in recent years. Traffic numbers and length means that it will probably be required that it be built in two races or with its own evacuation tunnel. This will have a great impact on the costs of the tunnel solution. The study outlines several possibilities for crossing with bridges, look at the study at Rambøll above to look more closely at the solutions.

For all the solutions, connections to existing road networks are shown. Various conflicts with local communities and the environment are discussed at a relatively rough level, and cost assessments have been made for all outlined solutions.

The costs for the crossing are assessed at between NOK 2.1 and 3.3 billion, including building costs and VAT. As for the tunnel, the costs are based on one race. The cost of new road between Fevåg and Rissa is assessed at NOK 0.9 billion to NOK 1.1 billion, depending on the solution for the fjord crossing.

We believe the overview study provides a good basis for further work on the connection. The traffic analyzes indicate that connection will inflict insignificant traffic on the ferry connection Flakk-Rørvik. As for Fosen, this means that Bjugn, Indre Fosen, Åfjord and Ørland will form a large common housing and labor market, which will have a great impact on further development at Fosen.

Q & A about the Fosen Bridge in Trøndelag, Norway

Interview with Olav Ellevset (CEO Fosenbrua AS) per. December 2017:

Will there really be a bridge over the Trondheimsfjord?

-We think it’s just a matter of time. There is a great deal of work in Norway to adapt to and further develop technology for such crossings.

What is crucial for the project to be realized?

-We are working towards the project to be able to finance itself, so this is the main challenge. With today’s framework the toll-free loans have to be paid back in 15 or 20 years. We work to adapt this to the lifetime of what is being financed. For such large constructions it will be minimum 100 years. We believe that the repayment period for short-term loans should be changed to a minimum of 40 years. Another issue is the practice for value added tax. Municipalities are able to refund this. But if the project is financed and implemented by a company, then today’s rules are interpreted so that refunds are not possible.

When will the bridge be finished?

-We believe it will be finished within a 10 years.

Will there be expensive toll rates?

-We assume that it will not be more expensive than today, preferably less.

What will the bridge look like?

-Several types is possible, and relevant suppliers from the shipbuilding-, the steel- and the construction industry are invited to come up with technical concepts. A low floating bridge is the solution that will be cheapest.

Will there be walking and cycling crossings?


What are you working on right now?

-The main task now is to find which way of funding that can be probable over 40 years. Norconsult is starting their work on traffic forecasts right now. The aspirations  of the business industry and the aspirations of municipal authorities for growth and development are crucial. Rambøll is starting with an overview study for the crossing of the Stjørnfjord. The work on influencing the overall financial framework for such large projects is an ongoing project.  In this matter we are working with other crossings in Norway.

Who are in the Board of Fosenbrua AS?

-Ove Vollan (Sparebank 1 SMN) is Chairman of the Board. Eigil Erbe (Attorney Company Erbe & Co), Elin Harbak (Johs. J. Syltern AS), Ragnar Lyng (Lyng Gruppen AS), Ola Setsaas (Stadsbygd Sparebank), Siri Stjern-Strøm (Stjern AS), and Olbert Aasan (Indre Fosen Invest AS) are board members

Will there be any work for local entrepreneurs on the bridge?

-The project includes not just the bridge over the Trondheimsfjord, so that is highly likely.

Can businesses and ordinary people help make the bridge be realized?

-Of course, it is important that there is an overall agreement at Fosen behind.

What are the largest effects of the bridge over the Trondheimsfjord?

-With bridges over the Trondheimsfjord and the Stjørnfjord large parts of Fosen will have a common living-, service- and labor market with the Trondheim region. Today’s population of 25,000 citizens can be expected to double. It will be a question how long it will take, 30, 40 or 50 years to double the population. It is important that the municipalities prepare for growth so that they can manage unfortunate effects through planning.

Technology Conference: Simpler, environmentally friendlier and safer travel

Technology Days 2017 focusing on smart roads for green transport

Statens Vegvesen arranged Technology Days Oct 17-23, 2017 in Trondheim

-There were many relevant topics for Fosenbrua AS, says Olav Ellevset (CEO of Fosenbrua AS). -Ferjefri E39 was a major theme. We learn that Denmark has modernized their financing system for large infrastructure projects. We need this in Norway as well! This includes a 40-year payment in toll roads as well as national guarantees.

-Many of those working on transport infrastructure are present at this annual event. Contact with people in the industry confirms our assessments so far of the cost level for the construction of floating bridges, says Ellevset.

Møte NTNU 27.april 2017

Meeting at Dep. of Civil and Environmental Engineering, NTNU

-We would like to cooperate with the Fosenbrua project, says Carl Thodesen (Head of Department of Civil and Environmental Engineering, NTNU)

Fosenbrua AS by Olav Ellevset (CEO) and Olbert Aasan meet representatives from the Department of Civil and Environmental Engineering, NTNU

At a meeting on April 27, 2017 there were discussions about the use of Experts in Team (EiT), student assignments at bachelor and master’s level and experience exchange. This can e.g. revolve around the technical aspects of building bridges, environmental aspects, economics and implementation models.

Ola Lædre (Associate Professor of Department of Civil and Environmental Engineering, NTNU) sees several tasks for bachelor and master students in connection with the Trondheimsfjord crossing. This may be different types of contracts, partnerships, etc.

-We seek knowledge and improvements of the positive aspects of the Fosenbrua project, says Olav Ellevset (CEO Fosenbrua AS).

-We are aware of various technical variants of the crossing. This is a large project with possible impacts on the entire region. Therefore we will use the knowledge at NTNU to try to get all sides of the project.


We have reduced our ambitions slightly compared to the national road network. As of today we use figures between NOK 700,000 to 1 million ex. VAT per. meter as the cost for a low floating bridge. However, we need political agreement on the repayment of toll loans over 40 years.

Relevant topics are ship passages, ship collisions, tide forces and wind, climate change, safety, lifetime and so on.

Automation of steel processing

-The steel price may only account for 15% of the cost of the steel construction, says Ellevset. -This means around 85% is processing costs. Managing automation of the forming process of steel will reduce costs. Automated laser welding will give an even quality of the product. How can we make the shipbuilding and steel industry invest in production lines for fjord crossings? It might be necessary for the authorities to get involved.

Socioeconomic effects

When a new bridge connection is opened, traffic will change. It will have social impacts like a larger housing and labor market. With the Trondheimsfjord crossing the distance between Brekstad and Trondheim will be less than 1 hour (today over 2 hours). The socioeconomic benefits are higher attractiveness, larger value creation and productivity. The bridge can be a prerequisite for industrial establishments, says Ellevset. –Norconsult has made a report (NO) that shows that travel and transport times will decrease drastically for most of the Fosen region with a bridge over the Trondheimfjord.

We need supporters!

-We are grateful for the connection to NTNU, says Olbert Aasan (board member Fosenbrua AS and head of Indre Fosen Kommune Utvikling). -There is a suppressed traffic, especially from the Trondheim side of the fjord. The ferry departure schedule in evenings is frustrating for people. We are patriots and need supporters! We are very pleased with your the interest in the project!

Owners of the project

Today all shareholders in the company are affiliated to Fosen. Most are businesses and public (like Fosen Regionråd and Indre Fosen municipality). There are 60-70% private owners.

-Many believe this is the most important project for Fosen ever, says Ellevset, and it is likely to be a demand from the people to have a bridge over the Trondheimsfjord!

Implementation Models

Fosenbrua is a large project with large investments. Two NTNU PhD students has on an earlier occasion looked at various implementation models for different project sizes. This is about finding the appropriate contractual forms for such an extensive project. Part of the legislation of Norway and the EU also provides guidance and limitations.

Jardar Lohne (Scientist at Dep. of Civil and Environmental Engineering, NTNU) works on Klima 2050 and Prosjekt Norge.

Rolf André Bohne (Associate Professor Dep. of Civil and Environmental Engineering, Faculty of Engineering NTNU) works on building and infrastructure. -A relevant theme might be how much to allow for building to save transportion by investing more in the construction phase and reducing climate emissions. We are concerned with the green shift in several ways.

-If Fosenbrua has innovative technical solutions, there may be other crossings that can look into this project. The project will provide opportunities for employment, tourism and holiday homes. Fosen will be within shorter reach of Trondheim. We are interested in working with the Fosenbrua project, both through research-based education and through research funding for staff phD and PostDoc.
