Esri, a U.S.-based geographic information system (GIS) software company,  has used data from federal agencies and the American Society of Civil Engineers to create an interactive visualization of infrastructure development since 1800 by mapping all 618,000 active motor vehicle bridges in the United States. According to the visualization, while bridges tend to be clustered in and around major urban areas, a few areas that don’t have large local populations have bridge-dense areas, such as the Great Basin Desert in Nevada. 

Take a look.
