Topology of Center Cities

Because the Mega Cities were founded in a century when water transport was the primary means of commerce, their topologies usually are maximized with sides that have a water boundary. That is, they are either islands, peninsulas, on the side of bays or edges of rivers. So, in many cities, there are 1, 2, 3 and even 4 (Manhattan, Singapore islands) sides that are bounded.

This topology may have made sense 2 centuries ago, but in the 21st century, when expansion is needed, the old boundaries provide endless "problems" that need to be fixed with overabundant "infrastructure". Case in point is downtown Seattle. Urbists are forever waxing about the need for some new bridge or tunnel to fix the mess. However, the mess is self-inflicted when you realize that downtown Seattle is a peninsula, bounded by a bay, a lake and ship canal. If ever you were to pick the worse possible place for one of the central nodes of an area, the Seattle Peninsula would be it.
