America, for some time now, has forgone its great infrastructure projects. It was the railway that first spread the country out –- developing land, building cities at each stop. The railway soon gave way to the highway –- developing even more land, building even more cities at each exit. But, the highway has yet to give way. BLUEPRINT AMERICA looks at the country’s next infrastructure system and, at the same time, the state of the current system: From transportation –- car, bus, light rail, train and plane –- to the water supply to the energy grid to city development and planning. In recent years, America’s infrastructure neglect has been seen across the country –- levees failed in New Orleans and a bridge fell in Minneapolis. But, neglect is no longer the only reason to rebuild. As the country is in an economic recession, there is a call now to rebuild the American economy by rebuilding the American infrastructure. It is a new New Deal to the country. BLUEPRINT AMERICA reports on how rebuilding America’s infrastructure can both impact the economy and change the current landscape of the country.
