US highway endpoints: index to interactive map series
The map below shows all known endpoints of current and historic US routes. Clicking on any state will link you to an interactive map of that state. All of the endpoints shown below are also marked on the interactive maps, and on those maps you can zoom in as much as you wish... all the way up to full street-level detail. You can also switch to aerial-photo mode. However, I do recommend a high-speed connection to view the maps linked below... if you don't have one, you might prefer to use the static map index instead.
Using the map below, if you're trying to fit your cursor on one of the smaller states, you may find it helpful to know that Delaware is grouped with Maryland, and all six New England states are grouped together.
