Highways in Canada

[hipster duck]

This isn't a grave national problem, but I always thought that Canada's inability to keep a standard TCH designation all the way through was a sign of how fragmented our country was.

In every other country, the national highway is actually a system of major roads, such as the US highway system (e.g. US-101), Interstate highway system and the Autobahn/Motorway/Autoroute systems in European countries along with their national highways. In the US, they're maintained by the state, but they still have the same designation. If you cross from Califronia into Oregon on I-5, it's maintained by Oregon but it's still designated I-5.

In Canada, the national highway "system" is, more often than not, just one road, loosely designated.
