On this side of the walkway the signs tell you to walk on the right and that cyclists need to get off their bike. Perhaps the one-way walkways are because of the construction around the gate taking up a lot of the space?
It’s an interesting idea, but I feel like this situation has shown me just how much the human race can ignore rules: I watched a couple walk on the left side, not a care in the world. As I emerged on the other side, I met someone who was walking in the wrong direction as well, taking the path I just exited. Some days I feel like a lot of measures are just for political show. But okay. It is what it is.
So that you can understand what I mean by “Chinatown gate”, here is a photo from early 2017:
Ironically, it also had construction around it on that day, although a lot less than what you would see currently.
Did you know that gates like this are entirely an American invention? They were invented in San Francisco after the 1906 earthquake. Check out the episode “It’s Chinatown” on the 99% Invisible podcast to learn more.
