This map, showing the right-of-way widths of Toronto's major streets, is one of my favorite maps. It tells you so much about the scale of the city.

Even if you were entirely unfamiliar with Toronto, you could look at this map and gather from the width and spacing of its major arteries that the orange streets (20 meters) represent the oldest parts of Toronto and that the red streets (36 meters) represent the newer and more suburban parts of the city.

It's also interesting to think about this map in the context of other cities. Manhattan, for example, has a famous grid plan that generally contains north-south avenues and east-west streets. Most, but not all, of the avenues are 100 feet wide, or ~30 meters. And most, but not all, of the streets are 60 feet wide, or ~18 meters.

I tried to get Gemini to create a New York version of the above map using the same color legend, but it hallucinated and didn't give me what I wanted. So you'll have to use your imagination. Manhattan's avenues typically correspond to the dark blue lines on Toronto's map, and its streets are even narrower than the orange lines.

If you were to overlay these two maps at the same scale, you'd see at least two things: one, Toronto doesn't have the same kind of broad avenues cutting through its most urban areas (meaning it's harder to move cars around) and, two, Manhattan has a much thicker web of urban streets. Consider the density that exists on Manhattan's 18-meter-wide streets.

Toronto did not lay out its urban grid ahead of time like New York did with its Commissioners' Plan in 1811. In many ways, Toronto feels more like an accidental global city. But that doesn't mean we can't look at our urban grid today and decide what it wants to be for the next 200 years. I think that would be a good idea.
