It's worth mentioning that prefixes have been added in other provinces as
well:

- R (for Route) and A (for Autoroute) in Quebec (e.g. A 40, R 148)
- PTH (Provincial Trunk Highway), PR (Provincial Route, i.e. secondary
road) and Route in Manitoba (e.g. PTH 15, PR 241, Route 90)

Other than "Route" for metro routes in Winnipeg, the highway shields can be
determined algorithmically (in Manitoba, anything above 199 is a Provincial
Route; in Quebec, everything below 100 and above 399 is an Autoroute);
outside of Winnipeg, there is no chance of confusion as to which route
marker to use, as there might be in Ontario.
