Overview
- Operations are slated for the first quarter of 2026, with the opening stretch limited to Torrejón de Ardoz before a planned extension toward Alcalá de Henares.
- The scheme uses the leftmost lane without physical separation, activating it as Bus‑VAO via overhead panels and ground beacons during peak hours and returning it to general traffic off‑peak.
- Access is restricted to buses, cars with at least two occupants, motorcycles, and emergency or maintenance vehicles, with single‑occupant zero‑emission cars excluded unlike the A‑6 Bus‑VAO.
- Inbound entries will be at Torrejón (pk 18+600), Rejas (pk 13+600) and Canillejas (pk 7+700) leading to Avenida de América, with outbound entries at Arturo Soria/Josefa Valcárcel (pk 5+850) and the Eisenhower junction (pk 11+400) and exits at Canillejas (pk 9+100) and Rejas (pk 15+200).
- Enforcement will rely on license‑plate readers and occupant‑detection systems after an initial trial period, with projections of up to 25% faster peak trips, about 500,000 hours saved annually and roughly 900 tonnes of CO₂ avoided each year.
