From 29% to over 80% in two and a half years
If you're planning a trip to Bogotá and wondering how close Line 1 really is, here's the arc so far. When monthly progress tracking began in January 2024, construction stood at 28.98%, according to the City of Bogotá. By the end of 2025, that figure had climbed to 68.64% — nearly 40 points of progress in 23 months, according to Empresa Metro de Bogotá (EMB). The most recent figure available, as of June 30, 2026, is 80.37%, according to EMB and the City of Bogotá. This recap walks through how construction got there — for the full month-by-month detail, with a source for every update, see the construction progress tracker.
The end of 2025 set the pace
As of December 31, 2025, construction reached 70.72% — landing right on the target projected for that cutoff, according to the City of Bogotá and El Tiempo. That same month, the viaduct passed 10 km built, and dynamic train testing began on a 905-meter energized test track. At that point, 3 trains had arrived in Colombia, with a new one arriving roughly every 15 days.
A steady first half of 2026
February closed at 73.75%, steady growth to start the year, according to El Tiempo citing EMB data. A month later, on March 31, EMB confirmed construction had passed the three-quarter mark — "the project enters its home stretch," per the City of Bogotá (via El Tiempo). By April 30, the figure rose to 77.53%: the tenth of 30 planned trains arrived in Bogotá that month, the viaduct passed 13 km built, and stations 1 and 2 had their roof structure nearly complete, with doors already installed, according to the City of Bogotá.
Stations get real names — and start looking finished
The June 30, 2026 update, the most recent available, brings two milestones that aren't just percentages. First, residents voted on final names for three stations: Ciudad Kennedy, Timiza, and Santa Isabel, according to EMB. Second, Calle 26 – Atrio station was fully commissioned — the first new station to be 100% operational anywhere on the project. Test trains, meanwhile, now reach Station 4 at 90 km/h. That same update puts total progress at 80.37%.
This June update also includes a data point that isn't about construction at all: 9 in 10 Bogotá residents say they're optimistic about the project, according to the 2026 Perception Survey cited by EMB and the City of Bogotá.
What's next
With construction past 80% at the midyear mark, the two dates EMB is still tracking are the test run — marcha blanca, a period of operational testing for the whole system — expected in September 2027, and commercial opening, expected in March 2028. As we cover in detail in the guide on when the metro opens, these are forecast dates, not a guarantee — they can shift as construction progresses.
This recap will be updated whenever the City of Bogotá or EMB publish the next official figure. To catch every update, the construction progress tracker has an RSS feed with each monthly figure, and you can browse all Line 1 stations in the meantime.
