The E4 highway project is one of the largest road schemes commissioned in Sweden this decade. The highway is a key route that links the Danish border in the south of the country with the Finnish border in the north.

AECOM redeveloped a 31-km section of the E4 highway between the towns of Ljungby and Toftanäs as part of a major contract for Trafikverket, Sweden’s national road and rail administration. Work included extensive and advanced Building Information Modelling (BIM), widening the road to meet Swedish expressway standards, delivery of preliminary and detailed designs and site monitoring.
