Since the late twentieth centuty, publicly-funded projects have taken place to reform urban land use through reorganizing urban infrastructures in major U.S. cities. This article examines the impacts of the Central Artery/Third Tunnel Project (popularly known as the Big Dig) in Boston, Massachusetts, USA through real estate and demographic changes of the neighboring communities. While the construction was still underway during the 1990s, white, English-speaking college-graduates who have relatively high income expectation increased in neighborhoods near the project site. It is suggested that the Big Dig Project triggered a gentrification process.
