摘要

The US 93 reconstruction project on the Flathead Indian Reservation in northwest Montana represents one of the most extensive wildlife-sensitive highway design efforts to occur in the continental United States. The reconstruction will include installations of 42 fish and wildlife crossing structures and approximately 15 miles (24 km) of wildlife exclusion fencing for a total investment of over $9 million. This report documents the success of using a context-sensitive approach to collaboratively redesign a rural highway within a multiple use landscape that accommodates the needs and concerns of different institutions, cultures and priorities. Further, this report introduces baseline field data collection methods and results that are being used to evaluate how the wildlife crossing structures and wildlife fencing affect deer- and bear-vehicle collisions and movements in a multiple-use rural landscape. The preconstruction data summarized here, and in combination with complementary post-construction data, will address the following goals of the evaluation study: (1) determine what effect US 93 wildlife crossing structures and fencing have on the frequency of animal-vehicle collisions and successful animal highway crossings; (2) document the design decision-making processes and lessons learned as a case study; and (3) identify best management practices and further research.
