The budget for Metro Line 3 in Belgium has skyrocketed to 4.7 billion euros, doubling from its original estimate of 2.25 billion euros in December 2021. What factors contributed to this significant increase? As of March 21, 2025, the details reveal a complex mix of inflation, construction challenges, and project expansions.
- Metro line 3 cost rose to 4.7 billion euros
- Albert-Noord section costs 1.334 billion euros
- North-Bordet section estimated at 3.2 billion euros
- Tunnel construction costs increased due to issues
- Rolling stock budgeted at 173 million euros
Why Did the Cost of Metro Line 3 Double in Belgium?
How can a public transport project see its costs double? The answer lies in various complications and rising expenses associated with the metro line’s construction.
The Breakdown: Costs Associated with Metro Line 3
The total estimated cost encompasses two main segments: Albert-Noordstation and Noord-Bordet. Each section faces unique challenges contributing to the overall budget increase.
Albert-Noordstation: A Complex Project
The segment from Albert to Noordstation is now projected at €1.334 billion, up from €699 million just two years ago. Key reasons include:
- Inflation affecting material costs
- Unforeseen reconstruction needs at Zuidpaleis
- Compensation claims from local businesses
- A remaining budget of €977 million yet to be spent
Noord-Bordet: Uncertain Future Costs
This part of the project is estimated at €3.2 billion, with most funds still unallocated. Factors influencing these estimates include:
- Tunnel excavation costs previously underestimated by Beliris
- Additional expenses related to safety systems and station equipment
- A new tunnel under train tracks costing significantly more than initial projections due to technical difficulties
The Bigger Picture: Infrastructure Spending Trends
This surge in costs reflects a broader trend impacting global infrastructure projects, including those in the U.S., where cities are grappling with similar financial strains as they modernize their transit systems.
