New York’s famous transportation icon, Grand Central Station (more properly Grand Central Terminal) celebrated the 100th anniversary of it’s opening on February 2, 2013. This rail terminal is more than just a means of travelling from point A to B, but it is a romantic, and grandiose metaphor for the hustle and bustle of American life. While the structure is definitely a cultural and architectural monument, it is also an engineering marvel, a fact recognized in 2012 by ASCE when it named it a National Civil Engineering Historic Landmark.
While the centennial of the GCT is being celebrated, a new project is taking shape approximately 90 feet below the existing tracks. The East Side Access project (ESA) will provide a new connection from the Long Island Rail Road (LIRR) to GCT. This project will help…

Urban miners have been busy constructing a new water supply tunnel underneath New York City to supply the megalopolis with the water it needs. The miners, or sandhogs as they are known, are about halfway complete with the new tunnel which is expected to be in service by the year 2020. Work on the 60-mile tunnel began in 1970 and the total projected cost is $6 billion and is widely regarded as one of the most complex public works projects in the western hemisphere. When complete, it will help deliver 1.2 billion gallons DAILY to 8 million New Yorkers.
