There are a lot of connected buildings in Minneapolis/St Paul too. Makes extra sense if you're in cold climates.
I like the idea of Skyways from a walkability perspective, but there are a lot of societal problems with them because they are not public rights of way. 99 Percent Invisible did a great episode about it here.
Houston has over 9 km of underground tunnels too, connecting the western side of its downtown.
Minneapolis is the largest contiguous with 15.2 km. Calgary seems to have some that are islands and not connected to the greater network.
Toronto has PATH, an underground network connecting office buildings, and Montreal has RESO/Underground City.
TIL. That's really cool.
