The world's largest wildlife crossing
When it opens in December, the Wallis Annenberg Wildlife Crossing will be the largest in the world.

It could also serve as a model for other projects, as crossings of this kind have often been viewed as too large to be effective. So, will the crossing work? We examine the construction and the existing scientific data to find out.
