            Bridge over Koberný Pond and a Wildlife Corridor
          
        
        
          The Bridge over Koberný lake and a wildlife corridor at the 87,500 km point of the D3 motorway section
        
        
          running from Tábor to Veselí nad Lužnicí, with a total length of 552.8 m, is located in a non-built-up
        
        
          area which is used for agricultural and breeding purposes.
        
        
          The motorway corresponds to the category D 27.5/120. The concrete pillars, with the cross-sections of
        
        
          8.0 x 2.5 m, are founded on 19 30-metre piles 1.2 m in diameter.
        
        
          Two pairs of casting carriages were used for the free-cantilever-method construction of the load-
        
        
          bearing structure of the box girder with the variable depth ranging from 2.69 m to 5.89 m. Casting of
        
        
          the girder proceeded symmetrically from 16-metre long balance arms.

          Metrostav a.s. is a universal construction company, which commands a leading position in key
        
        
          segments of the Czech construction market and also in market expanses of foreign countries. The
        
        
          company traditionally holds a strong position in underground construction, public and residential
        
        
          buildings, industrial construction and transportation construction. It is a member of the multinational
        
        
          DDM Group.
        
        
          Division 4 of Metrostav a.s. was founded in 2001 for the purpose of carrying out transport-related
        
        
          construction projects, particularly roads, motorways and railways including associated structures. Since
        
        
          2003, the division has been collaborating with a bridge production plant owned by Metrostav a.s. on
        
        
          steel bridge structures and steel-composite bridges. An important technological advance took place in
        
        
          2004, when Metrostav a.s. started delivering highway structures using its own capacities. Since 2006,
        
        
          the free cantilever technique has been developed in collaboration with the world’s leading companies in
        
        
          the area of the development of casting carriages.
