Disclosure: AI-generated visual.

Dubai has started the main tunnelling phase of the Metro Blue Line, marking an important step in one of the city’s biggest public transport projects.

On 3 May 2026, Sheikh Mohammed bin Rashid Al Maktoum launched the primary tunnelling works at the International City 1 station site. According to official Dubai sources, the Blue Line is a AED20.5 billion project that will add a 30 kilometre route to the network, including 15.5 kilometres underground and 14.5 kilometres above ground. The line is scheduled to open on 9 September 2029.

Quick Answer

The Blue Line is being built to connect growing residential, education, and business areas with the rest of Dubai’s metro system. It will link to the Green Line at Creek Station and the Red Line at Centrepoint Station. Areas on the route include Dubai Festival City, Dubai Creek Harbour, Ras Al Khor, International City, Dubai Silicon Oasis, Dubai Academic City, Mirdif, and Al Warqa’a.

How this stage works

The centre of the tunnelling phase is International City 1, planned as the largest underground interchange station in the Dubai Metro network. The station will cover more than 44,000 square metres and is expected to handle around 350,000 riders a day.

RTA has named the tunnel boring machine Al Wugeisha. It is 163 metres long, weighs more than 2,000 tonnes, and can move forward by around 13 to 17 metres a day. Tunnelling will continue from International City 1 in three directions: Mirdif, the Auto Market, and Al Warsan.

Why commuters may care

The Blue Line is not only about adding new stations. It is part of a wider plan to connect fast growing communities to public transport, ease pressure on major roads, and support the Dubai 2040 Urban Master Plan. Official project details also say the line will include 14 stations and is expected to serve districts with a projected population of around one million by 2040.
