A-3 (Madrid) is the principal autovía connecting Madrid and Valencia across central and eastern Spain. The route links the M-30 ring, the A-2 corridor, and the A-7 coastal axis while serving major urban areas such as Arganda del Rey, Tarancón, and Requena. It forms a key segment of the trans-European transport network that interconnects with routes toward Barcelona, Alicante, and the Mediterranean seaboard.
The autovía begins at the junction with the M-30 and the N-III in eastern Madrid and proceeds southeast through the Vicálvaro and Rivas-Vaciamadrid corridors toward Arganda del Rey. Past Arganda the A-3 traverses the Sierra de Altomira approaches before crossing the Almansa and La Mancha plains near Tarancón, linking with the A-31 and A-35 networks. Further east it passes by Motilla del Palancar and Utiel en route to Requena, then descends toward the Valencia metropolitan area where it connects with the V-30 and the AP-7 Mediterranean motorway near the Port of Valencia. The A-3 intersects regional axes serving Castilla–La Mancha, Comunidad Valenciana, and provides access to logistics hubs, linking with rail corridors such as the Madrid–Valencia high-speed rail line.
The corridor follows the historic N-III alignment used since the era of the National Exhibition of 1929 infrastructure campaigns and the later Plan de Carreteras projects of the mid-20th century. Upgrading to autovía standard began during the late Francoist Spain period and accelerated under successive administrations including the UCD and the PSOE governments. Sections were progressively opened in the 1980s and 1990s, reflecting investments associated with European Community cohesion policies and preparations for events such as the Barcelona Olympic Games and the expansion of the European Union. The conversion alleviated bottlenecks at historic junctions near Arganda del Rey and modernized crossings over rivers with structures inspired by projects overseen by agents linked to Instituto Nacional de Técnica Aeroespacial and regional planning bodies in Castilla–La Mancha.
Major interchanges include the initial junction with M-30 and access to the A-2 for northern Spain, a strategic interchange near Arganda del Rey that connects with regional roads toward Guadalajara, and a mid-route node interfacing with the A-31 toward Albacete and Alicante. Eastbound, the A-3 meets the A-35 and regional highways serving Utiel and Requena, before the complex V-30 interchange in Valencia providing links to the AP-7 and the Port of Valencia logistics areas. These junctions coordinate with freight routes bound for the Mediterranean Corridor and connect to feeder roads leading to industrial parks near Torrejón de Ardoz and San Fernando de Henares.
The A-3 supports high commuter volumes between eastern Madrid suburbs such as Rivas-Vaciamadrid and the capital, and sustains intercity flows to Valencia for passenger traffic and freight movements tied to the Port of Valencia and inland distribution centers. Seasonal peaks occur during holidays linking Madrid with coastal destinations like Gandia and Denia, increasing demand alongside connections from the AP-7 corridor. Traffic composition includes private vehicles, intercity coaches operated by companies serving Valencia Estació del Nord routes, and heavy goods vehicles supporting supply chains for sectors such as agriculture in Castilla–La Mancha and manufacturing in Valencia and Alicante provinces.
Infrastructure along the A-3 encompasses multi-lane carriageways, grade-separated interchanges, and reinforced pavements adapted for high axle loads from freight traffic. Notable features include river crossings over the Jarama and the Júcar with bridgeworks designed to EU standards, service areas providing amenities linked to brands and associations in the logistics sector, and intelligent transportation systems interoperable with national traffic management centers in Madrid. The corridor integrates noise mitigation measures near residential zones like Arganda del Rey and environmental protections adjacent to natural areas in Sierra de Chiva and sections of the Júcar basin.
Planned upgrades focus on capacity enhancements, safety interventions, and integration with the Mediterranean Corridor freight strategy promoted by the European Commission. Projects under discussion involve widening bottleneck sections, modernizing interchanges near Valencia to improve connectivity with the AP-7, implementing advanced traffic management systems consistent with Spain's General Directorate of Traffic policies, and coordinating with regional authorities in Comunidad de Madrid and Comunidad Valenciana for sustainable mobility measures. Longer-term proposals consider multimodal logistics terminals linking the A-3 with high-speed rail freight initiatives and smart infrastructure pilots funded through EU cohesion instruments.
