General information about the project
The works were part of the Swedish Transport Administration’s long-term strategy to maintain Sweden’s bridges. Renovation was done in stages and traffic was converged into 5 lanes during the works. In stage 1 summer 2016 we renovated the easternmost driving lane. Stage 2 related to the westernmost lane and was done in summer 2017. For the concrete and railings we used the Bridgecare method, working from a suspended scaffold on the bridge.
