A few days ago I wrote a post talking about what happens when you demolish an urban highway. It was a link to an article giving 5 examples of cities that have removed their urban highways and benefited.
After I wrote the post, a number of people responded on Twitter. Some thought it was a great idea and gave examples of other cities, such as Detroit, that are thinking about doing the same. But others responded and said that I was out of line. And that while it might work in some cities, it simply isn’t a viable option in cities like Toronto.
So as somebody who believes we should be taking down the Gardiner Expressway, I thought it would be worthwhile to revisit the topic and provide a bit more information.
To be clear, I’m not suggesting we remove the Gardiner and replace it with nothing. My belief is that we should replace it with a broad surface street that would still move lots of cars, but that would make our waterfront much more open and accessible to everyone.

So how is this feasible?
Again it comes back to the concept of
induced demand
. Back in 2009, two economists from the University of Toronto and University of Pennsylvania – which are actually both of my alma maters – published a study called
In it they discovered something really fascinating: there’s a near perfect relationship between new roads and highways built and the total number of miles driven. In other words, as cities increased road capacities (during their study period of 1980 to 2000), the amount of driving went up just as much.
What this should tell you is that trying to build your way of out road congestion is usually a losing proposition. That’s why every large city has a traffic problem. Try and think of one that has solved this. And as much as it might seem intuitive to tell people at cocktail parties that your city simply needs to build more roads and highways, it’s typically not that simple. (In my view, the solution is road pricing.)
The other really interesting thing that this study revealed is that it works both ways. When you reduce road capacity, drivers start to disappear. People choose to live closer to where they work. People choose transit. People go into the office at different times. People make all sorts of different decisions in response to this road change, just as they do when there are more free roads available to them.
So within a reasonable band (obviously you can’t remove all roads), there is no perfect amount of road capacity. If you added another lane to your highway, it would be full. If you took away a lane, it would end up equally full. That’s why removing the Gardiner Expressway isn’t lunacy.
Instead, it actually makes a lot of sense:
It’s the cheapest solution (compared to repairing it or burying it)
It would free up money for transit and other mobility solutions
It would make our waterfront more open and accessible
It would beautify our downtown
It would increase land values all along the waterfront
And since we’re still in the early days of developing our eastern waterfront, now is the time to do it. The longer we wait, the harder it’ll get and the more expensive it’ll get.
So I hope that the leaders in this city will think long and hard about this as opposed to immediately assuming we need an elevated highway to keep this city moving. The last time I checked, it doesn’t work so well in its current state.

This morning I explored Humber Bay Park, which is a waterfront park in the west end of Toronto. It’s in a neighborhood called Mimico that used to be a separate town, with its own mayor, until 1967. I honestly can’t remember the last time I was there, so it was fun to explore what felt like a new part of the city.
Given its proximity to downtown and the fact that it’s very well connected to the water, the area is currently facing tremendous development pressures. In fact, as I was standing in line waiting to order an Americano, the conversation happening directly in front of me was all about how developers are fighting to buy up every piece of land they can find. Normally I would chime in, but today I decided to stay silent.
Today the area is an interesting mix of old low-rise and mid-rise rental apartment buildings (many of which fell into decline a long time ago), and new high-rise condominiums that are all fighting for unobstructed views of the lake and downtown.
There wasn’t a ton of street or public life going on, but it was certainly a beautiful place to spend a Sunday morning. As much as I’m looking forward to getting back into snowboarding, I’m not quite ready for summer to be over. So I’m happy that we’ve been having some great weather in the city.
Today was my mother’s PDI for her new condo. For those of you who aren’t in the industry, a PDI is a “pre-delivery inspection” that happens about a week or two before you take occupancy of a new home. It’s basically a time for you to identify all the mistakes that the construction team has made and have them (hopefully) correct them before you actually move in.
But for someone like my mother who is making the move from a house that she’s lived in for decades, a PDI is actually something much more significant: It’s the first time she saw her new “home.” And a home is something much different than just a house or a condo – it has emotional significance.
It’s going to be an adjustment for her. One of the first things she did was open up the oven to see if she could fit her Christmas turkey in it. But in the end, I have no doubt that she’s going to love her new home. As I’ve mentioned before, people often overestimate the potential risks of change. But never be afraid to give up the good to go for the great.
