On November 30, 2025, the Metro de Medellín celebrated its 30th anniversary — three decades since the first trains rolled through the Aburrá Valley and changed everything. What began as a massive infrastructure project to address a city strangled by traffic has become the social spine of Medellín, a symbol of transformation, and an internationally studied model of urban mobility's capacity to reshape a city's identity.
The Metro de Medellín is Latin America's only aerial metro — almost entirely elevated above street level, running on concrete viaducts through the valley. This was a deliberate choice: the valley floor was too densely built to tunnel underground at reasonable cost, and the elevated design allowed the metro to avoid the city's complex topography while creating dramatic views of the Aburrá Valley that residents and visitors still find remarkable.
Today the system consists of 27 stations across two main lines (A and B), a total length of 34.5km, and an integrated network of Metrocable gondola lines that extend the system into hillside comunas that were previously disconnected from the city's opportunities. The cables are not just transport — they are powerful instruments of social inclusion, connecting informal settlements that previously took 90-minute bus journeys to reach to the metro network in minutes.
The Metro operates under what Medellín calls "Cultura Metro" — an explicit set of social norms around behavior on the system. Seats are given to the elderly and pregnant, no food or drinks are consumed on trains, conversations are kept at respectful volumes, and the stations and trains are treated with collective pride. The result: after 30 years, the Metro remains spotlessly clean, reliably on time, and safe.
International urban researchers have studied Cultura Metro as an example of how infrastructure can create and reinforce prosocial norms. The system is not just transportation — it is a daily shared civic experience for hundreds of thousands of people that actively builds community identity.
New tariffs took effect January 13, 2026. The Metro remains one of the most affordable urban transit systems in Latin America at under $0.70 USD per ride. The integrated Cívica card allows tap-on-tap-off across metro, Metrocable, Tranvía, and Metroplús systems.
The Metro's 30th anniversary was celebrated with construction actively underway on Line E — the Metro de la 80 — which will add 17 stations and 13.25km of new electric light rail through the western barrios, opening in 2028. The next 30 years will see a more connected, more equitable Medellín built on the foundation that the original 1995 decision created.
