The Central Artery/Tunnel Project (Boston, Massachusetts), also known as the "Big Dig", is providing many lessons for transport planners and engineers from all over the world. Designed to replace 7.5 miles of aging urban highway in the center of the city, the Big Dig has been compared in its extent and complexity to such engineering projects as the Panama Canal or the European Chunnel. Due to the innovative and unprecedented nature of the Big Dig, there has been broad interest in nearly every aspect of the project. To help facilitate the transfer of technology, the Federal Highway Administration has established the Innovations and Advancements Program to share knowledge gained from the Big Dig with the national and international transport communities. This article discusses some of the areas attracting the most interest among transportation professionals eager to benefit from lessons learned in the Big Dig project. These relate to tunnel jacking, slurry walls, immersed tubes, cable-stayed bridges, environmental mitigation, and partnering programs. |
