Abstract: The Norwegian Public Roads Administration (NPRA) is responsible for maintaining approximately 10,000 kilometers of public roads in Norway, which is roughly ¼ of the total amount of national and county roads. In 2020, NPRA was given the responsibility for natural hazard preparedness across the entire public road network in Norway. The primary task was to establish a 24/7 preparedness system to provide expert support during acute events. Additionally, a daily assessment of natural hazards risk on the roads is generated and disseminated to road owners who subscribe to the service. Over the years of its existence, the preparedness system has handled over 1100 inquiries. In 2023, 25% of these inquiries pertained to snow avalanches and slush avalanches. Consequently, natural hazard contingency plans have been a critical area of focus, aiding in identifying vulnerable road sections. These plans are essential tools for road owners and maintenance contractors, as well as for professionals providing expert advice during acute events. A purpose-built mapping tool called RESPONS is developed to assess and distribute the daily diligence-level for natural hazards affecting roads. Further development of the service will focus on online map-based contingency plans across digital devices for both contractors and professionals, more accurate forecasting, and increased safety for road users.
