Sweden Plans Road Upgrade to 74 Tons, Requiring Bridge Reinforcement
Quick Look
- Trafikverket plans to upgrade Swedish roads to handle 74-ton loads, necessitating reinforcement or demolition of around 600 bridges.
- A research project at Chalmers University of Technology aims to prove that heavy vehicles cause less stress than anticipated, potentially saving significant costs and reducing carbon emissions.

Why It Matters
Trafikverket intends to upgrade Swedish roads to accommodate a maximum load of 74 tons. This initiative would necessitate the reinforcement or demolition of approximately 600 bridges across the country.
Trafikverket vill uppgradera våra vägar till den högsta lasten, 74 ton. Det skulle innebära att omkring 600 broar runt om i Sverige måste rivas eller förstärkas.
Kan spara pengar och klimat om broarna inte rivs
Nu hoppas ett forskningsprojekt visa att tunga fordon inte belastar broarna så mycket som de dimensionerats för.
– Det skulle betyda att vi inte behöver riva alla dessa broar vilket sparar väldigt mycket pengar och koldioxidutsläpp, säger Rasmus Rempling, projektledare och professor vid Chalmers tekniska högskola.
