If this is where I think it is, I know a lot of it is to do with the freeway, but there are also some pretty significant upgrades to the cycling infrastructure going on. Fuck cars, of course, but its not all bad.
I was just about to ask whether it is simply closed for maintenance / improvements, which is the opposite of bad. Like, yes, it sucks that it is closed now. But do you expect them to never touch it again?
