Autopistas and autovías in Spain

The Autopista AP-51 (also known as Autopista Ávila - Villacastín and Conexión Ávila) is an autopista in the community of Castile and León, Spain. Opened in late 2002, it runs for 24 km (15 miles) between the Autopista AP-6 at the village of Villacastín, in the province of Segovia, and the eastern outskirts of the city of Ávila, parallel to the N-110. It then runs for a further 9 km (5.5 miles) as an autovía, the A-51, forming a partial beltway around the north of Ávila and connecting with the Autovía A-50.
