A strategic line between the north and south of the capital, the future line 3 of the Brussels metro is currently at a standstill. The cause: massive cost overruns, delays and a political impasse that’s holding up any decision. Here’s everything you need to know.
A key project for Brussels, now in jeopardy
Thought of as the backbone of the Brussels metro network, line 3 was to link Albert to Bordet in just 20 minutes. The plan was to provide better service for Schaerbeek, Evere and the northern districts, as well as welcome relief for already saturated lines. But after technical delays, controversy over emblematic buildings (notably the Palais du Midi), and soaring costs, the project is now seriously undermined.
Six scenarios on the table, no government to decide
The authorities have identified six possible scenarios, ranging from full completion to a total freeze on the project. The most costly (a public-private partnership) is estimated at 7 billion euros. On the other hand, outright abandonment would entail a loss of the 546 million already invested. An intermediate option, phasing the work in three stages up to 2046, seems the most likely. But with no regional government able to validate a scenario, everything is on hold.
An impact far beyond the metro

But the future of metro line 3 is about more than just mobility. The project is also linked to other major urban projects, real estate investments and development planning in the northern districts. Even partial abandonment would force Brussels to review its mobility strategy in depth. The next political meeting is scheduled for the end of August, but without a functioning government, the uncertainty is likely to persist.
