You know, Kuala Lumpur has a massively long pedestrian bridge that flows from one of the main convention centers throughout one of their districts connecting multiple hotels and shopping centers above the city traffic. Bangkok also has its pedestrian bridge connecting Central City, Siam Center, Siam Discovery, and multiple hotels/convention centers as well as Skytrain stations in its downtown district. Why don't we just build a major pedestrian network of bridges above the street grid?
