The potential for predators to use wildlife crossing structures for hunting could result in some species being preyed upon more frequently than elsewhere in the landscape. What would the consequences be if predators learn that hunting success is greater at wildlife crossing structures and develop preferences for these locations? Researchers and ecologists are frequently asked this question during the planning and design stages of road projects. Because there is no definitive answer to this question, the usual response is ‘it depends’, and the potential relevance of this situation should be assessed on a case‐by‐case basis.

    Wildlife crossing structures will be less effective for prey if their use is adversely influenced by predator‐prey interactions.

    The outcome of predator‐prey interactions at wildlife crossing structures may depend on the degree of co‐evolution between them.

    Our knowledge of specific interactions between predators and prey at crossing structures is scarce, and research is urgently needed.

    Roads and crossing structures should be designed to minimise potentially deleterious predator‐prey interactions.

    Altogether, the increased connectivity benefits provided by wildlife crossing structures for a wide range of species are positive, and the potential for predation should not be seen as a reason not to install such mitigation measures. The current evidence for predators using crossing structures in a systematic way to increase hunting effectiveness is scarce and controversial. However, the potential for such predation at or near crossing structures exists, and road planners and wildlife managers should aim to reduce this risk, particularly for rare species of prey.
