>>512665578A Mall in Philly was built like this, just nowhere near as tall.
It was connected to a regular department store on one two ends, and a train and subway station and concourse on the lower levels, as well as a couple skyscrapers that might have been twenty or thirty stories.
After a few decades the main mall was torn down, keeping the lowest level, and redeveloping the upper levels into a new mall that was only 4 stories, and didnโt require all the zig-zag traveling.
Iโm not really sure how much of the upper two levels are even occupied.
Personally I sort of liked the old zig-zag system, but it was hard to walk thru the whole mall in one circuit to see all the stores so there were corners were stores could be missed, and some mall goers found it hard to navigate.
Also, the department store at the one end closed, killing flow from that end to the upper levels.
The same thing had happened to a smaller mall in Philly two decades earlier.
