Dubai inaugurates $5.6 billion Metro Blue Line project with tunnelling works underway

Dubai has officially launched tunnelling works for its ambitious Metro Blue Line project, marking a major step in expanding sustainable urban transport infrastructure across the city. The project was inaugurated by Sheikh Mohammed bin Rashid Al Maktoum and is valued at approximately $5.6 billion (Dh20.5 billion), forming a key part of Dubai’s long-term strategy to build a more connected and environmentally efficient city.

The Blue Line will span around 30 kilometres and include 14 stations, connecting major residential, commercial, and emerging urban districts. It is designed to serve nearly one million residents and integrate seamlessly with existing metro lines, reinforcing Dubai’s broader public transport network and supporting population growth under the Dubai 2040 Urban Master Plan.

A major objective of the project is to reduce road congestion and shift commuters toward public transport, with authorities estimating a potential 20% reduction in traffic in key corridors. The metro line is also being developed in line with green building standards, making it one of Dubai’s most sustainability-focused infrastructure projects to date.

Scheduled for completion by September 2029, the Blue Line is expected to deliver long-term environmental and economic benefits, including lower emissions, improved mobility, and increased property value near transit corridors. As part of a broader transport expansion strategy, the project reflects Dubai’s continued investment in sustainable urban development and future-ready infrastructure systems.

A $5.6 billion metro expansion is one of the highest-leverage decarbonisation investments a city like Dubai can make - private-vehicle displacement typically generates larger cumulative emission cuts than most industrial decarbonisation programmes.
