Answer:
The Pan-American Highway
The Pan-American Highway is a series of roads and highways measuring approximately 19 000 mi or 30 000 km. It is not a single road but a series of roads and highways with some parallel sections and some spurs.
It was first proposed at the First Pan-American Conference in 1889 but as a railroad. This proposal was never realised. The concept of a highway was discussed at the Fifth International Conference of American States in 1923. This led to a specific conference in 1925 on the construction of such a highway but it took a further twelve years for Argentina, Bolivia, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Peru, Canada, and the United States to sign the Convention on the Pan-American Highway. Each country agreed to pay for the highway within their own boundaries. Mexico completed their section first in 1950. In 1966, the US Federal Highway Administration designated the entire Interstate Highway System to be an integral part of the Pan-American Highway System. There are spurs from the South American Pacific countries into Brazil and Uruguay.
