It'll be like if Columbia wa a pie, and the levels were divided like a slice, were each sections is a large area of the city. If you notice, the Sky-Lines almost circlate around the large area, instead of just connecting to every area of Columbia. It would make more sense like this in a story and gameplay perspective. If Columbia is just one giant level, most players would more likely go outside the missions like if it was GTA. However, much like how Rapture's buildings were large enough to be explorable, each of Columbia's level is pretty big enough to explore the buildings and areas.
