Blue Corridor, routes 301, 303 and 306 on Tacna, Garcilaso and Arequipa Avenues

The Autoridad de Transporte Urbano para Lima y Callao (ATU) administers a comprehensive urban mass transit network of complementary corridors serving the capital of Peru. Among these, the Corredor Azul operates routes 301, 303, and 306 along the major vial axis of Tacna, Garcilaso de la Vega, and Arequipa avenues, connecting the districts of Rímac, Central Lima, Lince, Miraflores, Barranco, and Surco.

In addition to the Blue Corridor, the ATU transit network includes other vital axes such as the Corredor Morado, which connects the densely populated district of San Juan de Lurigancho to central Lima and the Avenida Brasil, and the Corredor Rojo, which moves thousands of passengers daily between eastern Lima, Callao, and the capital's financial center via four main trunk routes.
