In Alaska, few highway improvement or construction projects have provided mitigation for wildlife crossings or invasive plant management. So when the Alaska Department of Transportation & Public Facilities (DOT&PF) initially proposed to widen shoulders, make alignment improvements, and add passing lanes over a 22-mile section of the Sterling Highway that bisects the 2-million-acre Kenai National Wildlife Refuge on the Kenai Peninsula, negotiations began in earnest. Traffic on this section exceeds 1.3 million vehicles per year, resulting in 168 wildlife-vehicle collisions during 2000-2007, 81% of which were moose, but also caribou, brown bears and black bears. Vehicle collisions now kill as many moose on the peninsula (~250 per year at a cost of $36,000 per moose) as are legally harvested by hunters! The Refuge seeks to maintain wildlife movement and migration across the highway even as DOT&PF sought to reduce moose-vehicle collisions while improving traffic flow. The interagency planning team worked collegially to accomplish both goals, minimizing the passing lanes to three ~1.5-mile segments and spending $10.5 million to construct six wildlife underpasses and 2.3 miles of 9-ft-high fence with 22 jump-outs every 1/8 mile. One of the underpasses is a new 140-ft bridge over the East Fork of the Moose River, an anadromous stream, designed to be 18-ft high to accommodate large ungulates. Construction started in 2017 and will be completed in 2019. The U.S. Fish & Wildlife Service helped offset mitigation costs for the $71 million project by providing $1.5 million in funds, $1.3 million in gravel, and $1 million from a Federal Lands Access Program grant for a pedestrian underpass between a parking lot and trailhead. DOT&PF provided $440,000 to study wildlife use of the mitigation structures, and to monitor and manage invasive plants five years post-construction, a first in Alaska. Additionally, DOT&PF used certified weed-free gravel (required) and top soil (when available), both firsts in Alaska. This collaborative approach to finding the middle ground while being willing to pursue alternative funding mechanisms has reset the bar higher for wildlife mitigation on the Alaska Highway system.
