Life in Culebrón

From trunk roads, main roads, and motorways, through to the tarmac ribbons in the countryside, the different sorts and standards of roads in Spain are owned and looked after by different levels of government. Most of the roads operated by the national government are the ones that cross provincial and regional boundaries. This includes both motorways and conventional roads. The motorways are divided into two types: autovías and autopistas. There are technical differences between the two types of road (such as the style of junctions, width of carriageways, design speed, and the like), for most Spaniards, autovía is the all-purpose word for motorways, and they reserve autopista for toll motorways.

There are a series of arterial roads that radiate from Madrid. The arterial roads have numbers prefaced by the letter N for Nacional/National. The six radial roads were given Roman numeral names, NI, NII, etc. As examples, the NIII goes to Valencia from Madrid. The NIV goes from Madrid to Seville and on to Cádiz.

Any main road, any national road, in the slice between the NIII and NIV, in a clockwise direction, will have a number that starts with N3. The NV goes to Badajoz from Madrid. Any road clockwise of the NIV but before the NV will have a name in the style of N420. Lots of u...
