J) Connect the East Coast to the West Coast overland for the 1 st time. Help develop city growth during Industrial Revolution and develop cities at major transportation nodes/intersections in the US. G) Link the interior of cities and provide a source of transportation for people living in the urban area. D) Use and growth of this system led to the construction of the Interstate Freeway System and promotes the growth of suburbs. Edge cities main source of transportation. E) Connects remote areas of the world. People able to travel/transport goods rapidly to other major urban areas.

Provides connection with popular cultural sources and promotes growth in urban services through entertainment programs and their marketing/advertising on mass scale for 1 st time. B) Allows for improved communication to remote areas through connective lines originally. Promotes suburban growth and later the counterurbanization movement. A) Connects remote/urban areas of the world by signals from space. Allows cities to develop around the space industry, communications, and broadcasting. I) Provides instantaneous contact with other urban areas. Allows access to services and goods w/o being in a urban area – promotes suburbanization & counterurbanization.
