How Milan's Transport Crisis Forced a Decade of Overdue Modernisation

For decades, Milan's transport infrastructure limped along on ageing systems designed for a city of half its current size. The Tangenziali—those infamous ring roads circling the city—were conceived in the 1960s when fewer than a million people called Milan home. Today, with the metropolitan area surpassing 4.3 million residents, those same roads move barely 400,000 vehicles daily through gridlock that costs the regional economy an estimated €2 billion annually in lost productivity and fuel waste.

The breaking point came in 2019. A particularly severe winter saw commute times on the A4 motorway from Bergamo to central Milan stretch beyond two hours. That same year, the M1 metro line—which carries roughly 800,000 passengers weekly between Sesto San Giovanni and Rho—experienced repeated signal failures, leaving passengers stranded for hours at stations like Lima and Loreto. Public frustration boiled over during a transit workers' strike that paralysed the city for three days.

These cascading crises forced Milan's municipal and regional administrations to confront uncomfortable truths. The metro network, expanded sporadically since 1964, had reached capacity limits. Bus routes serving sprawling neighbourhoods like Quarto Oggiaro and Niguarda were chronically underfunded. Suburban rail connections, theoretically linking satellite towns to the centre, were plagued by outdated signalling systems inherited from the 1980s.

By 2021, the confluence of EU funding mechanisms, post-pandemic recovery initiatives, and mounting political pressure coalesced into action. Milan's administration secured €3.2 billion in combined funding—roughly €750 per capita for the metropolitan area—to tackle three decades of deferred maintenance and expansion.

The M4 metro extension to Linate Airport, finally completed last year after seventeen years of construction, symbolised both the scale of the challenge and the possibility of breakthrough. The project's €2.4 billion price tag seemed astronomical when first proposed in 2006. Yet by 2026, its daily ridership of 95,000 passengers vindicated the investment, reducing airport shuttle bus traffic by 38 per cent.

Parallel initiatives—upgraded suburban rail to Como and Lecco, new tram lines through Porta Romana, the ongoing modernisation of Lambrate freight yards—represent not ambitious visions but rather delayed necessities. Milan finally confronted what planners had warned about for years: a modern European metropolis cannot function on infrastructure built for the 1960s.

The projects emerging now are less about grand transformation than triage—desperate remedies for systemic neglect that should never have accumulated in the first place.
