In the scope of the project “Förbifart Stockholm” a new 3-lane motorway is constructed, which connects North and South of Sweden’s capital Stockholm.
At a length of 1 km, the Hjulsta Södra creates an interchange, which includes two main bridges, two ramp bridges, three slab bridges and retaining walls.
The intersection is part of the Stockholm city bypass, which connects the southern part of the city and north with a new 3-lane motorway in each direction.
The section Hjulsta Södra includes the design of the following structures:
-
- Construction of two box girder main bridges each with a width of 16.00 / 15.15 m and a length of 629 m
- Construction of two ramp bridges each with variable width 8.65 – 12 m and length of 214 m / 260 m
- Construction three slab bridges with widths of 25 m / 15 m / 8.5 m and length of 70 m
- Construction of Retaining walls with a total length of 220 m
Structures present a specific challenge in planning and on the site.
The bridges cross the E18 motorway including the regional transport network, the Mälarbanan railway line, which will be extended by two to four trails during the construction period.
