Highway
Major highways are often named and numbered by the governments that typically develop and maintain them. Australia's Highway 1 is the longest national highway in the world at over and runs almost the entire way around the continent. China has the world's largest network of highways followed closely by the United States of America. Some highways, like the Pan-American Highway or the European routes, span multiple countries. Some major highway routes include ferry services, such as U.S. Route 10, which crosses Lake Michigan.
Hillclimbing in the United States
The hill climb with the longest road, that has been continuously run, in the world is the Mount Equinox Hill Climb located in Arlington, Vermont just outside Manchester. The length of the road is 5.2 miles and the elevation change is 3,100 feet. It contains more than 40 turns and cars have been clocked at breaking 100 MPH on the long straight ending at "The Saddle". The hill climb has been run by such famous drivers as Carroll Shelby, Briggs Cunningham, René Dreyfus, John Fitch and Miles Collier to name just a few. Started in 1950 as an official SCCA event, it continues uninterrupted, as a vintage car race. Since 1973 the sanctioning body has been the Vintage Sports Car Club of America.
