Bridge construction
Arsta Brücke
most economical solution for prestressing in the Arsta Bridge project. It was carried out in 38 concreting sections. In the bridge cross-section in the form of a bull's head there are 8 BBV L27 tendons, each running over two sections, four of the tendons each end at a concreting joint, where they were tensioned [...] connections through the new route network is to be doubled. In the area between Årsta and Älvsjö, the new 1.4 km long Arsta bridge was built using prestressed concrete and, when completed, would become the seventh longest bridge in Sweden.

This created a continuous tensioning system over the entire length of the bridge.[...]
