Overflight assistance

An overflight aid is a special form of animal crossing aid . This is a structural measure to ensure that birds and bats can safely fly over traffic routes . The most common construction technique consists of a mound of earth at the roadside to protect the birds. The wall forces the birds to fly higher as they cross the road so that they cannot collide with the passing vehicles.

However, because of the high costs, these measures are also viewed critically.
