The Interstate Highway System is the primary transportation network of the United States. The Interstate Highway System has succeeded and failed in certain ways in connecting the United States. It is important that new interstate highways are added so that the United States will be better connected. Several criteria are involved in placing new interstates. New interstates should follow the grid pattern of the existing interstates, with one end of the interstate in between existing interstates so that the interstate starts/ends west of one interstate and east of another (odd-numbered), or north of one interstate and south of another (even-numbered). Population of unconnected county seats, existing roads, and the elevation of unconnected county seats determine where new proposed interstates are placed. This project uses ArcGIS Pro, Google Maps, and Google Earth to map the findings and to create a better linked United States so that people are connected more efficiently. The results may be used in such a way that the USDOT or state departments of transportation can plan for the future.
