The "Route Nationale" refers to a network of national roads in France, designed to facilitate transportation and connect major cities. These roads are often marked with a green sign and are crucial for both local and long-distance travel. They serve as important routes for commerce and tourism, linking various regions of the country. Historically, the Route Nationale system was established in the early 19th century and has undergone several changes over the years. Today, many of these roads have been replaced or supplemented by autoroutes, which are modern highways. However, the Route Nationale remains significant for its scenic routes and cultural landmarks.
