Construction of a long bridge 10.11 on the S7 road – Zakopane

The specificity of the project: 

The purpose of the structure has been to lead the expressway through an area with is formation line located at a height that makes it impossible to build a road embankment (the elevation is over 22 m above the ground level). Moreover, the structure allows for an impact-free routing of the expressway over collector roads and unnamed watercourses. 

Length of the structure: 
  • Left: 430.62 m,
  • Right: 431.95 m.
The load bearing  structure of each roadway is a six-span continuous beam. The span girders were designed as a box section with variable heights from 4 to 5 m for the total span length. The superstructure was designed as single-chamber box girders. 
  • Number of roadways: 2.

The abutments of the structure were designed as a system of massive front and side walls. In addition, suspended abutment wingwalls are provided at the ends of the side walls. Separate abutment structures have been designed for each roadway, separated from each other in the dividing strip. 
One type of pillar of variable height up to 30 m has been designed for the load bearing structure, on which the supporting structure is based. All supports were founded with single foundations, directly on franki type piles.
