Urban sprawl that consists of a large number of commercial developments along a main roadway or highway connecting suburban housing and urban centers is called

The phenomenon you are referring to is known as "strip development" or "strip mall development." This type of urban sprawl is characterized by the spread of various commercial establishments—such as shops, restaurants, and services—situated along major roads or highways, often interspersed with residential areas.

Strip development typically arises as a response to increased suburbanization, where people move to the outskirts for housing while still seeking access to urban amenities. This form of development can lead to several challenges, including increased traffic congestion, environmental concerns due to urban heat islands, reduced agricultural land, and a lack of coherent community structure.

Additionally, the design of strip developments often prioritizes automobile access over pedestrian connectivity, leading to a less walkable environment. This reliance on cars can have broader implications for public health and sustainability. Urban planners and policymakers often strive to find a balance between accommodating growth and maintaining a high quality of life for residents through more sustainable development practices.
