During the construction of a 50 km-long section of highway in the Chaudière-Appalaches region of Québec (Canada), measures were taken to minimize the impact of the project on, and to facilitate its integration within, wintering habitat used by white-tailed deer. High fences and jump-outs, as well as safe wildlife crossings and other mitigation measures were designed and constructed, in several stages, over the 12-year period from 2004 to 2016. This article provides a description of the different systems used and the inherent challenges of each. Emphasis is placed on the various problems encountered and the alterations that were made with regards to their design and installation to overcome these. Suggestions are proposed for the designers of infrastructure projects seeking to implement similar measures, including the importance of determining the best location based on field observations made before and during the construction phase, and of issuing clear directives in all contracts and site surveillance documents, to ensure the protection of surrounding vegetation cover.
