Viabuild upgraded the complete bottom and top layer of the three traffic lanes on the A7 over a total of 7 km between Bergen and Saint-Ghislain. The 2 intersections on that route were also renewed near Saint-Ghislain and the R5 in the direction of Frameries. Work at the site was ongoing, seven days a week. Viabuild used a flexible work schedule with night and weekend work to deal with unexpected challenges.

During the works, for example, it became clear that the right traffic lane had to be deepened. Despite these setbacks, the strict deadline was met and Viabuild was able to complete the works as per agreement within 30 calendar days.
