The World Winter Service and Road Resilience Congress is a world-class event that builds on the work completed by the committees, made up of experts from PIARC’s member countries, in the last cycle; sharing experiences and international best practices culminating in presentations made by road experts, academia and practitioners from around the world including PIARC’s partners. Held every four years since 1969, the Chambéry Congress will be the 17^th edition. Winter issues related to road infrastructure and resilience in all seasons and climate thereof will be the major themes of this international meeting. We all have to contend with challenges due to the impact of climatic changes which concerns every country in the world, as well as the mitigation of climate change through the decarbonization of road infrastructure and road transport. PIARC's international experts have already done a great deal of work on these issues, so the Congress will be a forum for building new relationships, reconnecting with old and disseminating knowledge and sharing best practice and much more.
