Automatic summary, not yet reviewed
- The law organizes the State Road Network and divides it into a Basic Network (main routes carrying long-distance traffic) and a Complementary Network (the rest). It also creates the Adjacent Road System, made up of state roads outside the Network that can be transferred to other public administrations.
- Roads are classified as highways (autopistas), dual carriageways (autovías), multilane roads and conventional roads. The old category of fast road disappears.
- Before major road projects are approved, a cost-benefit analysis, multicriteria analysis to prioritize actions, and a study of the feasibility of indirect management or public-private partnership formulas are required.
- Road safety impact assessments are mandatory in studies for new roads, and safety audits must be carried out on projects and before works enter service.
- Four protection zones are established alongside roads: public domain, easement, affectation and a new building restriction zone, where construction is banned. In bypasses, the building limit line is set 50 meters from the roadway.
- Access to roads is strictly limited: on highways, dual carriageways and bypasses you can only enter or exit through their interchanges, and building or modifying an access without authorization is a very serious offense.
- Advertising visible from the road is banned outside urban sections, and the Ministry can order the removal of elements that affect road safety.
- Offenses are classified as minor, serious and very serious, with fines from €300 to €300,000. Very serious sanctions are imposed by the Minister of Public Works and expire after six years.
Who it affects
- Owners of land next to state roads: They cannot build in the building restriction zone and need Ministry of Public Works authorization for works in the other protection zones.
- Companies and individuals who want road access: They need authorization, and direct access to the roadway is often not allowed; doing it without permission is a very serious offense.
- Drivers and road users: Road safety is reinforced through audits and the removal of advertising that distracts drivers.
- Concession holders and road service companies: They must provide data to the Ministry, answer for service negligence and follow the rules for awarding service areas.
- Town councils: They receive road sections that become urban streets and must coordinate their planning with approved road studies.
Words worth knowing
- Dominio público viario (road public domain)
- Land owned by the State because it serves the road: the road itself, its functional elements and a strip of land on each side.
- Zona de servidumbre (easement zone)
- A strip of land next to the road where only works or uses authorized by the Ministry of Public Works are allowed.
- Contribuciones especiales (special levies)
- Payments due from those who specially benefit from a road project, such as owners of adjacent land.
- Travesía (road through a town)
- The part of a road that runs through a built-up area, with buildings along at least two thirds of both sides.
- Deslinde (boundary demarcation)
- The official procedure to mark the exact limits of land that is public domain of the road.
