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.

In the spirit of Startup Weekend, I thought it would be interesting to go back in time and pretend to pitch one of the most disruptive innovations of the 19th century: the automobile.
Typically pitches start by first outlining the problem. The idea is to make your audience aware of the pain point, so that they feel excited when you ultimately pitch your solution.
In the case of cars, the incumbent technology would have been horses. So I can imagine somebody standing up and talking about how horses are slow and how they drop stinky poo all over our city streets. And that the time has come for a revolution in personal mobility! Enough of this crap! :)
But while many of us probably can’t imagine a world without cars, try and put yourself in the shoes of somebody at the end of the 19th century who can’t imagine a world without horses. And then think about all the things we have subsequently done to make cars thrive:
We paved roads and created networks of freeways.
We invented rules of the road to ensure that people were operating these new devices properly.
We created a licensing system to ensure that anybody who was operating a car was doing so relatively safely and following the rules that had been created.
We created schools that taught people how to be better drivers.
We started insuring cars for when accidents inevitably happened.
We started having to accept fatal car accident and pedestrian deaths.
We had to give over large land masses to parking. In fact, we reorganized entire cities so that the car could be better accommodated.
And we setup government transportation divisions to make sure the needs of the car were always being met.
This is a long list of things we had to do to make cars possible and I’m sure there are many others that I have missed. Today, we all know how disruptive cars have been and we’re certainly questioning many of the things we have done. But we also accept this list as being largely normative.
However, before they were the norm, they were insurmountable challenges. How will we teach everyone how to drive these new cars? How will we minimize accidents? How will we make it easy for people to refuel their cars? Where will people store them when they’re not using them?
