Big Machines Make New York Dig

After three decades, the “tunnel to nowhere” under Manhattan’s East River finally has a destination: Grand Central Terminal. This article describes the 30-year project to bring the Long Island Rail Road into the east side terminal in order to offer Long Island commuters an option to Penn Station. Work stopped in the 1970s during the city’s financial crisis, but construction has begun again. The article explains how contractors are using three tunnel-boring machines for different tasks. The project should be completed in four years.
