During 2 winters we investigated the influence of transportation corridors on wolverine (Gulo gulo) movements through snow-tracking. Analysis of movements within the study area showed avoidance use of areas within 100 m of the Trans-Canada Highway and preference for areas >1100 m from the highway. Analysis of movements on the ski trail that formed the boundary of the study area showed a similar trend with avoidance of sections of the trail within 200 m of the highway and preference for sections >1100 m away. Mean width of the right-of-way for highway crossings by wolverines (68 m) was significantly shorter than that of approaches without crossing (165 m). Wolverines approaching the highway made repeated approaches and retreats and only crossed 3 out of 6 times. Wolverines did not hesitate to cross the Canadian Pacific Railway in areas where it does not share a common right-of-way with the highway. Our results indicate that Kicking Horse Pass is an important movement corridor for wolverines, however...
