What sort of environment protection measures have been taken in connection with the motorway?
The drainage water is lead away in coated ditches, preventing the eventually polluted water leaking into the ground water. The water is lead through oil separators and then - already filtered - to the closest naturally existing water streams or rivers. This is European practice to minimize the impact of road construction on the water circle. Further a protection forest is placed along the motorway to reduce air and noise pollution. In sensitive areas in addition noise protection walls were constructed. In order to protect the wildlife and to prevent crashes with animals a game fence was set up on both sides of the motorway on the entire length.
