Short description │
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.
