You’ve got Highway 1 in the south, Highway 2 in the north, Highway 3 even farther south than Highway 1, and then Highway 4 connecting rural communities on the west coast of Vancouver Island.
Just looking at those examples, it’s easy to see they’re certainly not related geographically, chronologically or by any other obvious connection.Both even and odd-numbered routes can run either east/west or north/south, so that’s not a distinguishing feature, either. So… what’s going on?
Well, as it turns out, the reason there doesn’t seem to be any logical connection is because there isn’t one.
There are general guidelines in place to help determine highway numbers, but the main thing we try to do when we assign a number is to make the road as easy to find and navigate as possible. Let’s check out some examples.
One of the most common ways a highway gets numbered the way it does is because it’s a continuation of a route from another jurisdiction. Highways 1 and 16, for example follow routes of the same number from Alberta, just as Highways 93, 97 and 99 follow routes of the same number from the United States.
New Route, Old Name
Sometimes, a new highway takes its number from a previously existing route. The new South Fraser Perimeter Road, for example, is now officially part of Highway 17, and the old route that ran between Deltaport Way and Highway 99 was re-numbered to 17A. The practice of using the “A”, which stands for “alternate” is pretty common when a highway gets moved.
Highway 118, also known as the Central Babine Lake Highway, which goes out to Granisle, is another interesting example. Why 118? Well, the road used to belong to the regional district, and it was District Road 118. The Province took it over, and kept the number 118 , since that’s how the road was known locally and referenced on maps.
It can also happen that a road number is requested by a stakeholder and approved by the ministry. Like Highway 113 – The Nisga’a Highway. The number 113 was requested by the Nisga’a, as it represents the number of years that passed to have a treaty signed by the government.
With so many numbered routes out there, this is just scratching the surface, but you start to get the idea of how they come about. Have you ever wondered about the number of a particular route?
