The greater Boston area expand from the Boston bay in a sprawling pattern. Due to the geography of the area, roads and highway networks spread out in a non-uniform pattern, following hills and rivers. Suburban developments followed the highway system, notably Marlborough, Framingham in the west and Quincy in the South. The sprawling developing pattern allowed residents of Boston to live in quiet suburban environment that is very much neighborhood oriented, while having access to downtown Boston via the highway system. The disadvantage is also clear, people can not get to anywhere when the highway system, namely 90 become congested.
