|The US highway system
The USA has an extensive system of interstate highways and state maintained roads. Some of the major highways are toll roads often called turnpikes, but most are free. All major interstate highways running north to south have odd numbers and are ordered from I-5 on the Pacific coast to I-95 along the Atlantic coast. All interstates running east to west are evenly numbered beginning with I-8 and I-10 near the Mexican border to I-94 near Canada.
