Abstract: Rv80 is the main road to Bodoe, the largest city in Nordland County in Northern Norway. The road is one of only two roads to the Bodoe peninsula, and every day more than 3 000 cars travel on the road. About 30 minutes outside the city is Ytre Kistrand, an area with several slush flow paths known to close the road almost every year. Usually the slush flows, a mixture of snow and water, have been small and only causing trouble for traffic without being a great danger to vehicles. In February 2021 everything changed when a contractor on duty for the Norwegian Public Road Administration was killed when a slush flow hit his car and threw it upside down on the railway 10 meters below the road. Two years later, in January 2023, an even bigger slush flow hit the road. The road was already closed by a smaller slush flow 100 meters away, and luckily the contractors managed to evacuate the vehicles in the runout zone in time before the road was hit. Construction of protective measures will begin in the fall of 2023.
