Linked Sky Bridges
One big thing to expect in many cities will be the need to have buildings connected to one another. This is likely going to be needed to avoid having to go outdoors and walk all over the place to get from point A to point B. It makes more sense to build sky bridges, where buildings link together. These buildings could be residential or they might simply be places that do similar things. Of course, any bridge at all would make sense. It does not have to be an enclosed territory and different buildings can make their own version of this. In our view, linked bridges will be an important part of what cities will look like in 2050.
