One of the characteristics of streets is that once you lay them out, they tend to be fairly permanent. This can be a benefit when you get it right, like in the case of Manhattan’s celebrated grid plan. But it can be a real challenge when you get it wrong, or when you’ve designed them around a particular use and you then later decide that you want something different. In my view, one of the greatest city building challenges around is trying to take a place that was designed exclusively for cars and turn it into a place that is designed for pedestrians. That said, the above video by Spin is a great reminder that there are lots of things that can be done, and in some cases they don’t necessarily need to cost a lot of money. In this video, they transform an intersection in Salt Lake City into a safer and more enjoyable place for pedestrians and for people riding bikes and scooters.
