Centennial of NY Grand Central Station…And What the Future Holds
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…

Seattle Light-Rail Tunnel Likely to Break Ground This Year

The project will involve twin bored tunnels on the order of 3 miles in length. It is scheduled to open for use in 2016.
There is another notable tunnel project associated with the Seattle Light Rail, known as the Beacon Hill tunnel which I have blogged about before.
