More than 20 kilometers of plastic barriers are in place to direct the crabs away from the island's main roads and into its 31 underpasses and on a five-meter-high bridge. These pathways also make it easier to see the crabs do what they do best, and they have become a popular tourist attraction. (Source)
The mass destruction of bee populations around the world has already forced farmers in the Chinese province of Sichuan to pollinate plants by hand. In the U.S., some are left with no choice but to rent hives transported cross-country by truck to cross-fertilize their crops. (Source)
6World's Longest Overpass
The dark gray and yellow-spotted amphibians need to get to vernal pools on the west side of the road so they can mate, but their annual voyage was historically made treacherous by cars that would inadvertently crush some of the creatures each spring.
In the early 1980s, Amherst residents were so concerned about the amphibians that they formed a “bucket brigade.” In late March and early April, they stood along Henry Street to pick up roving salamanders and carry them safely to their breeding ponds.
In 1987, the British Fauna and Floral Preservation Society and ACO Polymer, a drainage company in Germany, heard about the salamanders' predicament and provided funds for an experimental tunnel project along the street. The underpass system allows the spotted salamanders, as well as wood frogs and other amphibians, to safely migrate back and forth.
These crossing structures are tiny — about 10” high and 6” wide. Each tunnel has a slotted top to provide enough of the dampness salamanders need to keep from drying out. Fences guide the critters inside the mouths of the underpasses. (Source)
8Ecoduct De Woeste Hoeve
As of 2012, the Veluwe —1000 square kilometers of woods, heath, and drifting sands — is the largest lowland nature area in North Western Europe. It contains nine ecoducts, 50 meters wide on average, that are used to shuttle wildlife across highways that transect it. Its first two ecoducts were built around 1985 across the A50 when the road was constructed. Five of the other ecoducts on the Veluwe were built across existing highways — one was even built across a two-lane provincial road. The two ecoducts across the A50 were used by nearly 5,000 deer and wild boar during a one-year period. (Source)

On March 19, 1963, after seeing too many squirrels being flattened, resident Amos Peters decided to protect squirrels and give them a way to cross a busy thoroughfare without getting killed by passing cars. The original sky-bridge was built over Olympia Way near the Civic Center in downtown Longview. Designed to look like a mini-suspension bridge, the 60-foot-long (18 m) span was made from aluminum piping covered with an old fire hose to create the roadway. The total cost of the bridge was $1000.

10Davi's Toad Tunnel
Rumor has it that the frogs initially refused to use the tunnel, so lights were installed to encourage them. They then died from the heat of the lamps inside the tunnel. If they did get through, they also had to battle with birds who quickly learned of the frog-producing hole in the ground. The project received national attention, including a feature on The Daily Show in 1998. In January 2000, the children's book, The Toads of Davis, written and illustrated by Ted Puntillo, Sr., was published to tell the story of the Davis Toad Tunnel through the eyes of the frogs. (Source)
