Mexico started the 20th Century with a Revolution; from 1910 to 1921 the Mexican Revolution was moved by the railways, which was the main transportsystem at that time, along with the hundreds of kilometers of roads and trails. In 1925 the National Roads Commission was created as the starting point for the transport infrastructure construction needed by the country for its future development. The road network grew from 1416 km in 1930 to 62,235 km in 1968, and by 1980 reached 213,000 km. Nowadays, with more than300.000 km the Mexican transport network is the circulatory system of a complex economy where transport is the fourth activity of economic importance according to the aggregate gross value, accounting for the movement of 80% of all national freight.
