 Recognizing that a need existed to improve its financial picture, Stone & Webster opted for a further change in its traditional marketing strategy.The company centered its hopes for future growth on a broader expansion of its core businesses into global markets, a cutback in its dependence on power generation, and the expansion of its environmental and transportation efforts.Stone & Webster's infrastructure and transportation activities during this time included the engineering and design of railway and other large transit systems, including part of the Washington, D.C. metro; major airport improvements in Denver and Miami; bridge construction, such as the eight mile-long bridge linking Prince Edward Island to the Canadian mainland; and roadway upgrading, including work on the New Jersey Turnpike.
