As urban sprawl continues to connect two cities through continuous development, the combined urban areas evolve into what is termed a megacity or metropolitan area. Particularly, when such a joining occurs, it can also be referred to as a conurbation.

A conurbation is a region that results from the merging of multiple urban areas, leading to a large continuous urban space. This phenomenon is often characterized by significant population growth and an increase in economic activity, along with extended transportation and infrastructure networks that connect the once-separated communities.

These developments can impact social dynamics, economic conditions, land use, and environmental management in the region, prompting city planners and local governments to adapt their strategies to accommodate the complexities of larger, interconnected urban areas.
