Access to communities and resource developments in northern Canada often relies on a single all-weather or winter road. Warming trends in recent years can put these indispensable access routes at risk by impacting road structures that overlie permafrost, and by shortening the duration of winter roads built on ice or seasonally frozen ground. This paper presents two case studies of all-weather and winter roads in northern Canada to describe the issues pertaining to the impacts of climate change and the adaptation strategies that have been or are being implemented to cope with the impacts. The paper also discusses the aspects of seasonal truck weight limits that are vulnerable to climate change and possible adaptation strategies.
