The US has two national highway networks:

* The Interstate Highway System, major high-speed roads connecting
  major cities.
* The United States Numbered Highway System (commonly referred to as
  the "US Highways"), medium-speed roads routed to connect as many
  settlements as reasonably possible.

Detecting from extent also runs into the problem that Interstate spur
and loop routes almost never cross state lines.
