On 15 August at the latest, the Tretten bridge in Gudbrandsdalen collapsed. Now research from Her\u00f8y can prevent that from happening again. It is connected to an old bridge in Nordland. The Her\u00f8ysund bridge was completed in the 1960s and then became a link between two islands in Her\u00f8y municipality. About two years ago, the bridge was to be restored. But due to serious injuries, the work was stopped. – It was during that work that we discovered that it was not possible to repair the damage that had occurred on the bridge. HAPPY PROJECT: – Today we have a one-way bridge. Now we will have two lanes and pavements on the new bridge, so both traffic and soft road users will be taken care of. Photo: Sofie Retterst\u00f8l Olaisen \/ news This is what project manager in Nordland County Municipality, Terje Krommen, says. Despite major rust damage that weakens its load-bearing capacity, the bridge is in active use by the Her\u00f8yfjerdingen. But it is also important for both Norwegian and international researchers. – Extend the lifespan by 30 years The Her\u00f8ysund bridge in Her\u00f8y municipality on the Helgeland coast is to be used as a test pilot in a new research project. But does that mean that it is risky for the islanders to use the bridge? It is actually safer now than before. Now it is continuously monitored: Nine sensors have been installed in the Her\u00f8ysund bridge. They continuously monitor the condition of the bridge. In addition, they provide information that can be used to predict the condition of other bridges. Photo: Per Ove Ravants\u00e5s Since September 2020, the bridge has been equipped with sensors to gain knowledge of how the condition of the bridge develops over time. The aim is to find methods to uncover almost invisible damage early on. It will also be important information that researchers can use about other, similar bridges. Not only will the result be of great importance for safety. The findings can also have a positive impact both for the environment and the wallet. ENVIRONMENTAL ASPECT: – Releases environmental emissions with what comes when a new bridge is built. A rehabilitation measure does not have that environmental impact, says Per Ove Ravats\u00e5s Photo: Sofie Retterst\u00f8l Olaisen \/ news Had the damage to the Her\u00f8ysund bridge been discovered earlier, the bridge could have stood for another three decades. Per Ove Ravats\u00e5s, responsible bridge and wharf manager in Nordland County Municipality, believes so. – If we can get started early on with measures on such bridges, we can extend their lifespan by 30-40 years. Then we won’t have to build a new bridge. Ravats\u00e5s emphasizes that with more knowledge, there will be fewer measures needed for bridges around to have a longer lifespan. – We need to gain a little more knowledge about the bridge, so that we can manage, operate and maintain bridges in a better way. Will make digital twins of the bridge Many people have taken an interest in the project. Nordland County Council and the Norwegian Public Roads Administration are the main players, but they include SINTEF, NTNU and UiT. Daniel Cantero, is the project manager for the research in the project and says that, among other things, they will engage master’s students at NTNU to contribute to the research. – It is a perfect laboratory, he says. – We often only work in the lab, that is not the reality. It is a good opportunity to try out theses. STUDENTS CONTRIBUTE: – NTNU is the largest university in Norway with technical subjects. Therefore, we want students with master’s theses to contribute knowledge to research, says Daniel Cantero at NTNU. Photo: NTNU The students at the universities will, among other things, create digital twins for the bridge. In this way, they can simulate how both the Her\u00f8ysund bridge and other concrete bridges will develop over time, and how they react to greater loads. – In addition, we can research the condition of, among other things, steel inside the construction to predict where and how they will develop. OLD: Cantero says that research on infrastructure has not been prioritized to a large extent in Norway until now. But many of the bridges in the country are already 50 years old. Photo: Sofie Retterst\u00f8l Olaisen \/ news Cantero hopes the research on the Her\u00f8ysund bridge will show that there is a need to spend more money on precisely this type of research. – A lot of money can be saved if we know more about our infrastructure. Some bridges may be in better condition than we think too. Can save 100 billion But the Her\u00f8ysund bridge cannot be restored, and must therefore be demolished. And the new bridge, which is coming up nearby, has a project budget of approximately NOK 300 million. – If we had started earlier with measures on this bridge, we could have taken measures for perhaps 10 million, says Per Over Ravats\u00e5s. ATTRACTIVE: Her\u00f8ysund bridge was ideal for the research due to the fact that, like many other bridges, it is built of concrete, and that there were already some interesting damages. Photo: Sofie Retterst\u00f8l Olaisen \/ news Although money has been lost, Ravats\u00e5s believes that the research can save the state billions. In total, there are approximately 18,000 bridges in Norway that are managed by the Norwegian Road Administration. And with better knowledge of maintenance, they can save a lot. – This could mean that we can achieve savings of approximately NOK 100 billion in Norway. On the Her\u00f8ysund bridge, grave rust has been discovered on the tension cables. It is one of the damages that the researchers are now learning more about, with the bridge as a pilot project. Photo: Per Ove Ravants\u00e5s The research project can have major ripple effects and has already generated national and international interest. – What we discover here with this construction may be the same defects in other constructions, says Krommen.
