In recent years, pessimism about the U.S. infrastructure has been growing, notes Wharton real estate professor Gilles Duranton, a specialist in urban and regional development, transportation and local public finance. “More and more, it is said that the overall infrastructure is old and decaying, that bridges collapse and roads are full of potholes. Water poisons residents in some places like Flint, Michigan; electricity is not always reliable; airports and seaports are under strain; cellphone coverage is piecemeal.”
