Several bridge elements have now been lifted onto land. There they are cut up and examined more closely. It is still unknown when and how the over 50-tonne lorry stuck on the bridge will be removed. Head of transport in Innlandet Aud M. Riseng says they must proceed carefully. – Now it is important to do things wisely so that you secure the evidence you need to find the cause. Because if the bridge collapses as it is now, then the evidence is destroyed, she says. At 4pm on Wednesday, a large part of the collapsed Tretten bridge in Øyer was lifted away. The work was carried out with a crane.

A truss from the bridge that was lifted away on Wednesday afternoon weighed 15 tonnes. Difficult work The job of removing the truck and the bridge has proven to be both difficult and risky. – We have to make continuous risk assessments along the way. The safety of those doing the work is the most important thing, says Riseng. The lorry has to leave before they can remove more of the bridge over the E6. – The original plan to remove the lorry was too risky as the bridge is now, on an incline. Now the safety assessment is that the bridge must come down and it must happen in a controlled manner, says Aud Riseng. ON THE BRIDGE: The lorry driver had arrived in the middle of the Tretten bridge when it collapsed.

In the middle of the bridge It was Monday morning 15 August that Tretten bridge in Gudbrandsdalen collapsed while a car and a lorry were out on the bridge. There was one person in each vehicle. Both emerged from the incident unharmed. The lorry driver, Terje Brenden, had the worst working day of his life when the bridge he was driving on collapsed. – I thought I was going to die, he told lastebil.no. Brenden, who made it to the middle of the bridge before it collapsed, saw the asphalt begin to ripple up and down in front of him like an earthquake. RESCUED: The driver of the lorry who was on the bridge when it collapsed was rescued on Monday by a rescue man who was hoisted down from a helicopter. A truck and a car were out on the bridge when it collapsed. Setting up temporary bridges The glulam bridge was nearly 150 meters long and 10 meters wide. The Norwegian Public Roads Administration found a fault on the now collapsed bridge during an inspection in 2016. On Tuesday evening, it was decided to close 14 wooden truss bridges, pending the cause of the bridge collapse at Tretten becoming clear. The bridges are located in Viken county (8), Innlandet county (5) and Nordland county (1). The Norwegian Public Roads Administration is now working to install temporary bridges to replace some of the 14 closed truss bridges. These are the places where the closure has the greatest consequences for road users, they report in a press release.

Demanding work Prosecutor Hans Petter Ommedal in the Innlandet police district says that it is a demanding job to find out how the bridge could collapse after only ten years. Norwegian bridges are designed with a lifespan of 100 years. – It is the NOK 1,000 question that we are trying to find out, he says. Thirteen bridge Thirteen bridge collapsed on the morning of 15 August 2022. A car and a truck were on the bridge. The bridge was opened on 15 June 2012. The bridge replaced the old steel truss bridge from 1895 at the same location. The new bridge was a wooden truss bridge with two lanes and a pavement. Thirteen bridges carried county road 254 over Gudbrandsdalslågen and the E6. The bridge had a width of 10 metres. The main span was 70 metres, in total the bridge was 148 meters long. The bridge was of the same type of construction as the Perkolo bridge at Sjoa which collapsed in February 2016. Thirteen bridges are classified in the road lists as a BK (use class) 10–60 road. That means 10 tonnes of axle pressure and 60 tonnes of total weight. COLLAPSE: The Tretten bridge is completely destroyed.
