TransMilenio

TransMilenio is a bus rapid transit (BRT) system that serves Bogotá, the capital of Colombia, as well as Soacha, a neighbouring city. The system opened to the public in December 2000. As of 2024, 12 corridors containing 99 bus routes totalling 114.4 km (71 mi) run throughout the city. It is part of the city's Integrated Public Transport System (Spanish: Sistema Integrado de Transporte Público; SITP), along with the urban, complimentary, and special bus services operating on neighbourhood and main streets. TransMilenio consists of several interconnected BRT lines, with raised floor stations in the center of a main avenue, or "troncal". Passengers typically reach the stations via a bridge across the street. Typically, four lanes down the center of the street are dedicated to bus traffic, with the outer lanes allowing express buses to bypass buses stopped at a station. As of 2025, the trunk line system was circulating 1,825 buses on average. An additional set of 876 regular buses, known as "feeders" (alimentadores), carry passengers from certain important stations to many different locations unreachable on the main route. Unlike the main TransMilenio buses, feeders operate without dedicated lanes, are not articulated, and are either green or blue (regular TransMilenio buses are red). There is no additional fare to use the feeder buses. There are 27 bicycle parking facilities in main TransMilenio stations with 7,351 parking spaces to facilitate cyclists using the system. Eight BRT corridors were certified in 2013 to meet the BRT standard with excellence: Autonorte and Caracas received silver certifications, while Americas, Calle 80, Eldorado, NQS, and Suba received gold.
