Storsjön lake is one of the biggest in Sweden and during warmer months ferries traverse it at the fullest. However, with the cold weather the lake transforms into giant ice highways. Every year when the ice thickness reaches 7.9 inches, the seasonal bridge is prepared and maintained. It should be noted that there is a limitation on vehicle weight (only weights of 2.0-3.9 long tons or 2.2-4.4 short tons). However, this is definitely a spectacular experience that will give you a bit of a shiver.
