• Description:
• The subject of the work is the removal of the existing constructions of the Bílina crossing along the Ervěnice Corridor and their replacement with a simple open meandering watercourse bed. The solution includes other measures to ensure migration permeability for aquatic animals, ensuring access for maintenance, etc. The construction consists in the creation of a riverbed close to nature, which will replace the original crossing of the Bílina River.

The Bílina transfer is carried along one of the floors of the dump in a DN 1200 steel pipe. The length of the pipe is approx. 4 x 3 km.
