To help accommodate the growth in rail traffic, the Boston and Albany constructed two large rail yards, one in the Allston section of city and another adjacent to the Lennox Hotel on Huntington St, adjacent to the Back Bay. While the Boston and Albany and its contemporary railroads were constructing new yards, other factors that would foreshadow the decline of the city's fortunes were manifesting themselves through the late nineteenth century and into the early twentieth; traffic to the Port of Boston declined, necessitating the Federal government to dredge the main shipping channels and construct new piers to handle larger vessels; AT&T moved its operations and headquarters from Boston to New York in 1910. The problematic relationship between the city and the business sector under the successive mayoral administrations of James Michael Curley drove a wedge between these businesses and the municipal government, souring employers on Boston. Adding to these problems, a series of economic recessionary periods culminating with the Great Depression coupled with a heavy tax burden sent the city's finances into a tailspin. Despite minor uplifts from the mobilization of the two World Wars, by the end of the World War II the city was in dire straits. Much of the state's infrastructure west of Boston was in a serious state of decay, with the major east-west Routes 2 and 9 in need of significant upgrades. At the same time, rail traffic in the region was becoming financially untenable to utilize for material transportation for newly emerging technology companies of the era due to the railroads’ outmoded pricing structures and limited geographical reach.
