Prior to the invention of the locomotive (train) and the automobile, people primarily traveled by ship across waterways.  Therefore, it was very important to build your city along a river or coastline, not only for easier farming, but also for easy access to trade routes.  However, once cars and trains became common, travel across mountains, deserts, and other less hospitable areas became much more accessible.

Looking at the inset map above, you will notice that major cities have developed along the junction of two or more highways.   In fact, you will notice that none of these towns are situated along a major river at all. While water is still important for survival, it became less important for travel allowing settlers to have more choices for urbanization.  

As urbanization increased, manmade features such as highways, bridges, and railroads were created to facilitate transportation and movement of goods and ideas between cities and outlying areas. Manmade features are important to locations where natural features and resources are limited.
