Km of regional and provincial networks

To calculate the length of the paved road network, the kilometres of the different networks are added together. The following shall be considered: Motorways (AR) and ring roads with motorway status, regional roads (not including entrances/exits of AR and RN, car parks, etc.), regional roads (including entrances/exits of motorways and national roads, car parks, etc.), all provincial roads, bridging municipal roads, excluding, in principle, agricultural roads and footpaths and main roads included in the municipal network (previously provincial). Note: the length on 1 January of year x is assumed to be equal to that on 31 December of year x-1). the important thing is to know that this data is valid on 1 January of each year.
