The International Finance Corporation (“IFC”); a member of the World Bank; has been approached by the Agencia Regional de Movilidad (ARM) to act as transaction lead advisor for a brownfield PPP aimed at expanding; rehabilitating; and ensuring the long-term operation and maintenance of one of Bogotá’s most strategic western gateways: the Avenida Calle 80 corridor; between the Calle 80 Terminal and the Bogotá River; with extensions up to the Siberia intersection. The project seeks to enhance mobility and public transport quality along this highly congested corridor; which currently serves over 320;000 daily passengers; while promoting operational efficiency and climate-resilient infrastructure. The project is divided into two main modules.Module 1: includes the expansion of the Medellín Highway with a third lane between the Bogotá River and the Siberia intersection; as well as the construction of a new three-lane bridge over the Bogotá River to connect with the ongoing Calle 80 interchange works. Module 2: covers the expansion and adaptation of approximately 7.7 km of corridor between Calle 80 and Siberia; incorporating exclusive BRT lanes; mixed-traffic lanes; pedestrian bridges; new stations; and complementary urban infrastructure; along with the relocation of the TransMilenio depot to new facilities near Siberia.
