Question

Use the map to answer the question.

A map of the eastern United States depicts the region from north of Boston to south of Washington, D.C. The majority of the area shown on the map is a metropolitan statistical area, with portions scattered throughout labeled micropolitan statistical areas.

Examine the figure.

In one sentence, identify the geographic term used to describe the Boswash corridor, depicted in the map.
In 1–2 sentences, describe this urban structure and identify at least one of its key challenges.
In 2–3 sentences, analyze one feature of sustainability as it relates to the Boswash corridor.

Answer 1

The map depicts the BosWash corridor as a megalopolis (a linear, polycentric urban corridor).

This urban structure is a contiguous string of large metropolitan areas from Boston through New York and Philadelphia to Washington, D.C., forming a densely populated, economically integrated conurbation; a key challenge is severe transportation congestion and aging infrastructure that strains regional mobility, air quality, and housing affordability.

One sustainability feature is transportation: the corridor’s high population density and short intercity distances create strong potential for efficient public transit and high‑speed rail to cut vehicle miles traveled and greenhouse‑gas emissions, but fragmented jurisdictions and continued suburban car dependence make coordinated investment and system integration difficult — overcoming these barriers through regional planning, transit‑oriented development, electrification, and expanded rail service is critical to improving the corridor’s long‑term sustainability.
