Milan's Transport Future: What City Leaders and Experts Are Saying About the Metro Extension and Beyond

Milan's transport infrastructure is undergoing its most ambitious transformation in decades, with multiple projects reshaping how millions of commuters and visitors navigate Europe's financial capital. From the ongoing Metro Line 4 expansion to innovative tram corridors in the Navigli district, local officials and transport experts are articulating bold plans to reduce congestion and emissions.

The M4 metro extension to Linate Airport represents a cornerstone of Milan's strategy. Currently, the line extends from San Babila toward the airport via a route through Porta Romana and the eastern suburbs. Transport authorities have consistently emphasised that the €1.7 billion project will eliminate approximately 40 percent of airport shuttle traffic on the A4 motorway by 2028, according to statements from the Agenzia delle Entrate and Azienda Trasporti Milanesi (ATM). Completion is expected within 24 months.

Beyond the metro, city planners are championing a controversial but strategically important tram modernisation in the Navigli neighbourhood—Milan's historic canal quarter south of the Duomo. Officials argue the €280 million investment in expanded tram networks along the Navigli Grande and Navigli Pavese will create a genuine alternative to private vehicles in an area that currently absorbs significant afternoon traffic. The project aims to connect the Navigli directly to Porta Genova station and the Centrale hub.

Meanwhile, cycling infrastructure continues to expand. The municipality has pledged to add 90 kilometres of protected bike lanes by 2027, with particular focus on the Viale Monza and Corso Buenos Aires corridors. Transport planners have noted that cycling already accounts for 9 percent of daily trips within the metropolitan area—nearly double the figure from 2015—and officials believe targeted investment could push that to 15 percent within five years.

However, challenges remain substantial. Congestion costs Milan's economy an estimated €3.2 billion annually, according to analysis from the Chamber of Commerce. Air quality in areas surrounding the Tangenziale ring road and along major arteries like Viale Fulvio Testi continues to exceed EU pollution thresholds on roughly 120 days per year.

Transport academics from the Politecnico di Milano have urged the city to accelerate integrated ticketing systems across metro, tram, and bus networks—a recommendation officials say they are actively pursuing. The consensus among planners is clear: Milan's future as a liveable, competitive global city depends on successfully executing these interconnected transport projects within budgetary and temporal constraints increasingly difficult to meet.
