I love how the Atlantic Cities article starts, they use the phrase "only in New York", which is very appropriate in this case! Foundation drilling has commenced for a project that will create 26 acres of developable space by creating a deck over the top of a Long Island Rail Yard serving America’s busiest train station, Penn Station. Over 300 drilled shafts extending 90 feet down to bedrock will be constructed to support a continuous concrete deck that will span over the entire rail yard (check out the photo and video below!). High-rise buildings and other structures will be built over this deck to form the neighborhood that the developers are calling Hudson Yards. The area of the track where the 30 LIRR tracks converge into 4 lines that enter Penn Station will have a steel truss bridge with about 150 ft span length.
