According to project documents, the project development objective (PDO) is to improve readiness and start the implementation of the Bogotá Metro Line 2 (BML2). Under BML2, the Bank is supporting the construction of a 15.5-kilometer metro line, which will improve connectivity and access to services for residents in the northwest of Bogotá, and it is expected to be integrated with other transport systems in the city. BML2 is expected to support climate mitigation by facilitating a shift to electric public transport and promoting active transportation. 

The project will be co-financed with other Multilateral Development Banks (MDBs), including the European Investment Bank (EIB), the Inter-American Development Bank (IDB), the Banco de Desarrollo de América Latina (CAF), and the private sector.
