Building the bridge underpass on Hwy 21 is one of many efforts across North America to reduce the number of vehicle and wildlife collisions.

The body of work focused on providing safe passage for wildlife in and around roadways is growing every year. The following web sites provide a place to start learning more about what is being done to protect people and to protect wildlife.

Safe Passage was written for engineers, biologists, and conservationists in the Western United States and Canada who are working in the field on wildlife crossings on a day-to-day basis.

Parks Canada – Banff National Park – In response to high and rising traffic volumes, sections of the Trans-Canada Highway (TCH) have been upgraded from a two-lane to a four-lane divided highway in Banff National Park.  To reduce the negative impacts of a larger highway on wildlife populations in Banff National Park, numerous overpasses and underpasses have been installed.

Underpass in Montana

The former rail underpass in Montana provides adequate space for large animals to cross below the highway.

Federal Highway Administrationprovides examples of how transportation agencies are reducing highways’ impact on wildlife and fish. This website developed by FHWA highlights more than 100 success stories form all 50 states.
