Here is an interesting study that looked at the impact of urban highways on social connections within the 50 largest US cities. To measure this, the researchers used Twitter data from 2012-2013, which is a period of time where the default setting in the mobile app was to tag each tweet with the user's precise geographic coordinates.
This allowed the team to generally figure out where a user is likely to live. If you're often tweeting from the same residential address, then there's a good chance that's home. They then looked at things like mutual followship as a measure of social ties. And what they ultimately found was that in all 50 cities, urban highways exhibit a strong barrier effect. They measured this using something they call a "barrier score."
Now this sounds right and supports lots of other evidence that highways divide cities; but Twitter isn't necessarily a place where mutual followship means you actually know the person in real life and you regularly walk down the street to see if they can come out and play. So one of the things that the researchers also did was work to replicate their findings using data from another social network called Gowalla.
I very vaguely remember this platform, but it is/was a social network where users are supposed to connect with people they actually know and share their locations through check-ins. With this data they found that their "barrier score" was even more pronounced, which makes sense given that the platform's social graph should have had, in theory, stronger real-life ties.
But even if you don't believe the social data, these results should make intuitive sense. Highway underpasses and overpasses tend not to be the best environments for pedestrians. They're usually a clear break in a city's urban fabric, which can make people second guess whether they really want or need to cross it.

Last month, I wrote about Toronto's proposal to add additional "Avenues" to its urban structure. ("Avenues" is a defined term that I touch on in last month's post). Well, this week the new Avenues Policy went to City Council for debate and approval. You can read all the back and forth via Matt Elliott on X. Not surprisingly, some Councillors were/are opposed to it, fearing it will create some sort of dystopian future for Toronto. An attempt was made to send it back for further study and consultation, which is the typical delay tactic. Comments were made that people in multi-family buildings are lonely because they don't know their neighbors. And it was argued that Kipling Avenue should not be a designated "Avenue", even though it's already called one. (Toronto street suffixes can be weird sometimes.) Thankfully, the new Avenues passed. And this is a big deal for Toronto. Over time, this expanded Avenue network is going to create new housing and employment opportunities, and make transit and other forms of mobility far more viable all across the city. As I said last month, I think it's going to be foundational in helping us move away from the outdated model of the monocentric North American city. Slowly but surely we are laying the groundwork for an urban structure that is actually, and more uniformly, urban.

Now let's look at what Toronto has just proposed in terms of new Avenues (shown above in purple). This is the kind of thing that immediately gets me excited because, as proposed, it implies a significant upzoning for a large portion of the city and it creates a much more uniform urban structure. Here, we have a blanket of intersecting Avenues, which will open up a ton of new housing opportunities and make it far more feasible to build efficient transit and other mobility solutions across the city. In fact, I'd argue that this is one of the most important land use discussions taking place in Toronto today. It's foundational to moving us away from the anachronistic model of the car-oriented North American city.
Now we just need to make it happen, and then empower developers and builders of all scales to build housing and a mix of uses all along these purple lines. For more on this, check out the City of Toronto's Housing Action Plan.
