The N-1 (formerly designated as N-I) was the main road from Madrid to France in Spain. From Madrid, the road headed north to Burgos. In this section, most of the old N-I has been replaced by the AutovÃÂa A-1. From Burgos to Miranda de Ebro the N-1 still exists, running parallel to the (formerly tolled) Autopista AP-1.
In ÃÂlava, the former N-I has been redesignated. Current roads using the alignment of the former N-I include the and , the western and eastern access roads to Vitoria-Gasteiz. In the province of Gipuzkoa, the road is still signed as N-I despite being an autovÃÂa. The N-I in Gipuzkoa is tolled for heavy goods vehicles.
