I don't ever see it happening, but Ontario needs to rethink the majority of its highway network and figure out the numbering system. It truly is a mess with county numbers, regional numbers, provincial numbers, etc. Basically the 400-series highways could be left alone, but everything else could be open for discussion.
It's ridiculous that somehow a provincial highway must be maintained by the province, rather than connect point a to point b. They had so many connecting links that did the job, and so many have been removed now or downloaded, creating gaps.
Highway 12 comes Durham Road 12 in the middle of nowhere. Highway 33 comes County Road 33 near Kingston, etc.
And then there are some very odd retained highways. Why was Highway 4, 73, 19, 59, and 24 all downloaded south of Highway 3, but Highway 6 keeps going to the metropolis of Port Dover.
How was Highway 41 between Highway 401 and Highway 7 downloaded, while Highway 37 was retained so close to Highway 62?
How is there such a huge no-mans' land of provincial highways in the 40 / 401 / 402 triangle? Here's a list of all former highways that used to exist in this area: 2, 4, 7, 21, 22, 76, 78, 79, 80, 81. All wiped out in the span of 8 months.
How does Highway 4 disappear through the City of London?
How was Highway 85 (used to be Highway 86) retained in Waterloo while Highway 126 was downloaded in London?
How does Highway 420 stop 1 km away from an international border crossing and become "Regional Road 420" for the last gap.
How does Highway 20 exist for less than 2 km and connect a stub of Highway 58 that doesn't connect to the other part of Highway 58, and the other end of Highway 20 turns into "Regional Road 20". How is there is no signage by the province letting vehicles know that Regional Road 20 continues just past Highway 20, in less than 2 km.
How is Highway 9 carved into two segments and connected with a Regional Road 109?
How does Highway 3 end within a few kilometers of the QEW and the Peace Bridge (Fort Erie)?
I know we live in a GPS based world, but a consistent numbering and wayfinding strategy still is very important.
It's really too bad that when the highway transfers were happening, they didn't consider changing the designation of what a "KINGS HIGHWAY" would mean, and instead, perhaps municipalities / counties to put their name above the route number in the space formerly allocated to "THE KING'S HIGHWAY". It would have retained the highway network, and still, after 20 years, downloaded highways in rural areas are called "HIGHWAY #" even if it's designated as a different number as a regional road. Talk about confusing for newcomers or tourists.
On a final note, it is the MTO's 100th anniversary / birthday. Perhaps it would be wise to contact Minister Steven Del Duca to request the cleaning-up and restoration of Ontario's Highway system as part of the anniversary. Contact information here:
