 The bipartisan infrastructure law passed in 2021 allocates $350 million to build wildlife crossing structures nationwide, including $8 million for this one on Highway 93, where a fifth of all grizzly bears killed by cars in Montana die. Most wildlife crossings funded by the first round of infrastructure bill money are in western states, but road ecologist Kylie Paul says there are about half a dozen in the Midwest, southern, and eastern states.
