Road ecology blog: Wildlife fence and barrier wall associated with wildlife underpass for Key deer (8 m wide, 3 m high), US Hwy 1, Big Pine Key, Florida, USA. Most of this road section has a wildlife fence. However, where the roadbed had to be raised to allow for two underpasses, a barrier wall replaces the fence and takes over the function  of keeping Key deer from entering the road and guiding them to the safe crossing opportunity.

The open slotted roof allows for light, and air and soil temperature and humidity inside the tunnel to be similar to the surroundings.

Road ecology blog: Common toad (Bufo bufo) screens and buckets, Rijksstraatweg Elsterstraatweg N225 just west of Elst, Utrecht, The Netherlands. The stick allows small mammals to climb out of the bucket but the toads are stuck until volunteers ("bucket brigade") bring them to the other side of the highway during the breeding season (in spring). Second image shows male and female common toad (Bufo bufo) amplexus in bucket.

The barrier wall was under construction in the images (they were made in 2010). There is a concrete lip or overhang on the polymer wall.  Turtle mortality was reduced to zero or almost zero.
