The A-1 (also informally known as ; ) is a Spanish autovía route which starts in Madrid and ends in Irun. It replaced the former national road from Madrid to France, the N-1 road. It carries the designation of European route E05, and, as one of the major north–south arteries of Spain, is one of the country's busiest highways.
Between Burgos and Armiñón there is an alternative for this autovía, no longer toll, the autopista AP-1.
In 2011, work was ongoing to bring the section between Burgos and Madrid up to modern standards.
Sections Autovía A-1 currently has two sections: one between Madrid and Burgos and another between Miranda de Ebro and Alsasua. Traffic through the 49.6 km discontinuity between Burgos and Miranda de Ebro is redirected to the N-I. Beyond Altsasu, traffic continues on the N-I to the French border.
