With the city expanded beyond the borders of Manhattan, and with the rapid progress in transportation networks all over the country, New York City needed to make better transportation infrastructure. Development of Grand Central Terminal and Penn Station was the answer to the growing city and regional needs for civic train network. To enrich the area of the city with these two stations, the city also builds the New York Public Library.

The importance of civic infrastructure development in a city like New York is crucial how for the people who live in New York City, but also to the people who are visiting the city. Without proper and adequate transportation infrastructure the city will collapse. That is why the development of Grand Central Terminal and Penn Station was something that helps the city to further develop in one of the biggest cities in the world. Architects also pay attention to other details, like economic activity of the stations which will allow sustainability and long-term maintenance of these civic assets. They also put effort to make these places to be built in a unique style, using neo classic style as a base for the Art Deco architectural style. They used iron and glass for the windows, and Tennessee limestone with the marble for the inside of the buildings.

To make Penn Station, Grand Central, and New York Public library as one whole part of the civic architectural and cultural wonder of the city, city officials, private partners, and architects made very complex buildings using symmetry and thermal windows which bring extra lights in the buildings. They made interior composition very profound with several levels of steps and ceilings that intercept on multi-levels. In Grand Central, we have a beautiful ceiling with astrological signs with the lights that represent starts which gives the building that profound complexity and uniqueness. Outdoor space for each building is projected to find a contrast from busy streets. An example of that is the terrace that surrounds the library and the Bryant Park behind the New York Public Library.

Without these three buildings, the city will not be just in a collapse with public transportation, but also this city will lose the enrich quality of life which these buildings provide. There will be lost of economic activity, tourism benefits and loss of public interest in this area. We can see that on the example of old Penn Station building which was demolished and instead of that we have cold and ugly buildings in this area which reflects on less economic, cultural and touristic interest in the area.
