NATIONAL ROAD NETWORK (RED VIAL NACIONAL): Its administration corresponds to the Ministry of Public Works and Transport (Ministerio de Obras Públicas y Transportes), which shall define it according to the requirements determined for that purpose by the Executive Branch, by way of an agreement (acuerdo). This network shall be constituted by the following classes of public roads:
- a)Primary highways (Carreteras primarias): Network of trunk routes, to serve as corridors, characterized by relatively high traffic volumes and a high proportion of international, interprovincial, or long-distance trips.
- b)Secondary highways (Carreteras secundarias): Routes that connect important canton capitals (cabeceras cantonales)—not served by primary highways—as well as other centers of population, production, or tourism, that generate a considerable number of interregional or intercantonal trips.
- c)Tertiary highways (Carreteras terciarias): Routes that serve as traffic collectors for the primary and secondary highways, and that constitute the main roads for trips within a region, or between important districts.
The Ministry of Public Works and Transport shall designate, within the National Road Network (Red Vial Nacional), restricted-access highways (carreteras de acceso restringido), on which access or exit of vehicles shall only be permitted at certain intersections with other public roads. It shall also designate freeways (autopistas), which shall be restricted-access highways (carreteras de acceso restringido), with four or more lanes, with or without a central dividing island.
CANTONAL ROAD NETWORK (RED VIAL CANTONAL): Its administration corresponds to the municipal governments (municipalidades).
It shall be constituted by the following roads, not included by the Ministry of Public Works and Transport within the National Road Network (Red Vial Nacional):
- a)Local roads (Caminos vecinales): Public roads that provide direct access to farms and other economically rural activities; they link hamlets and villages with the National Road Network (Red Vial Nacional), and are characterized by having low traffic volumes and high proportions of local short-distance trips.
- b)Local streets (Calles locales): Public roads included within the quadrant of an urban area, not classified as urban crossings of the National Road Network (Red Vial Nacional).
- c)Unclassified roads (Caminos no clasificados): Public roads not classified within the categories described above, such as bridle paths (caminos de herradura), footpaths (sendas), trails (veredas), that provide access to very few users, who shall defray the costs of maintenance and improvement.
(Thus amended by Law No. 6676 of September 18, 1981, Article 1).
