Ice bridge

There aren't many people that can say they've made use of an ice bridge. Especially within 60 km of a major metropolitan city. But At Oka Quebec, a mere 20km from where I grew up, there is an ice bridge every winter connecting Oka with Hudson, 2 kilometres across on the western shore of the Ottawa river. A ferry connects the two in summer, taking about 10 minutes assuming no waiting, but the drive across the ice only takes 3 minutes. To go around the long way through the west end of Montreal takes just about an hour - assuming no traffic - and is 61 kilometres.
