AECOM conducted the preliminary design and environmental impact assessment for the redevelopment of a section of Sweden’s E4 road. As it connects Helsingborg and Stockholm, the E4 is one of the country’s most important routes. The road also passes through the protected area for Bergaåsen, the source of drinking water for Växjö and Alvesta municipalities.

The 31-km stretch between Ljungby and Toftanäs was the only part of the E4 that was not of motorway standard. Trafikverket contracted AECOM to create a motorway link along the section with minimal impact on the local community and environment.

Our experts’ redevelopment work addressed four interchanges and 28 bridges (nine over and 19 along the E4, and two over rivers). It included widening the road to meet Swedish expressway standards, producing detailed designs and site monitoring.

Our BIM data environment enabled consultants in Poland, Sweden and the UK to collaborate seamlessly and deliver the project successfully. As a result of our work, we were nominated as a finalist in the Innovation in Roads category at the 2015 Bentley Be Inspired Awards.
