In 2004, Medellín – the second largest city in Colombia – introduced the Medellín Metrocable system to connect low-income residents to public transport. As the world’s first modern urban aerial cable car transport system, this innovative addition to Medellín’s existing metro system was built in response to significant spatial inequalities in metro access. Metrocable was designed to improve transport and quality of life in informal settlements located on the mountainside, home to some of the city’s most disadvantaged communities. The system currently consists of three lines, the first of which carries approximately 30,000 passengers per day. A recent study further speaks to the system’s success, finding that the Metrocable dramatically improves accessibility to metro stops and employment opportunities for some low-income residents. This attention to the city’s underserved communities reflects Medellín’s increased commitment to improving equity and quality of life while reducing emissions through sustainable mobility.
