Summary
Passage design: Badgers preferred simple tubes (diameter of 30-40 cm) with a slightly rough inner surface. Concrete pipes were effective and highly durable; (Armco) steel provided an alternative where ground subsidence was expected. This design was successfully used by badgers to pass beneath roads, even if over 100 m in length. A cornice fitted to the entrance helps prevent water from entering if the passage lies below ground level.
Fence design: Underpass effectiveness was highly dependent upon the quality and the length of fencing either side of the underpass entrance. Experience indicated galvanised, spot-welded wire mesh netting (mesh size 2.5 x 5 cm) to be a good fencing material. Fencing around 1 m high (posts positioned on the road-facing side) proved effective in preventing badgers from climbing over; digging the fence 20 cm deep into the ground with a 30 cm wide, horizontal strip of mesh attached to the bottom prevented them from burrowing underneath.
