The viaduct for the first line of the Bogota Metro will be completed before the end of 2026 [1].
This milestone is critical because it allows the city to move from the construction phase to operational testing. Without the completed viaduct, trains cannot perform the necessary trials required to ensure safety and efficiency before the system opens to the public.
Mayor Carlos Fernando Galán and the Alcaldía de Bogotá said that the infrastructure will be ready for trains to conduct tests for the first time [1, 2]. These trials are the prerequisite for the system to eventually begin transporting passengers [1, 2].
Progress on the project has remained steady. Construction reached an advance of 77.53% by the end of April [3]. This percentage reflects the overall completion of the infrastructure, including the progress of stations one and two of the system [3].
While the city has provided a timeline for the viaduct, the full operational schedule remains a point of contention. Some reports indicate that authorities have not yet announced an official date for the start of full passenger operations [4]. However, the completion of the viaduct remains the primary technical hurdle for 2026 [1].
The project represents one of the most significant infrastructure undertakings in the history of the Colombian capital. The transition to the testing phase marks a shift in the project's lifecycle from heavy engineering to systems integration.
“The viaduct for the first line of the Bogota Metro will be completed before the end of 2026.”
The completion of the viaduct is a technical necessity that separates construction from operation. While the city can now project a window for testing, the lack of a firm passenger start date suggests that while the 'track' may be ready, the broader systemic integration—including signaling, power, and rolling stock certification—may still be subject to delays.
