Dubai Metro Blue Line tunnelling begins: the districts to watch before 2029

Work has started on the tunnels for the AED 20.5 billion Blue Line, a 30 km, 14 station metro due to open on 9 September 2029. Which districts it serves, how transit tends to move property values, and what to check before buying.

On May 3, 2026, Sheikh Mohammed bin Rashid Al Maktoum, the Ruler of Dubai, launched tunnelling on the Dubai Metro Blue Line, the next major extension of the city's rail network. A tunnel boring machine, a giant drill that excavates and lines a tunnel as it moves, began work from the future International City 1 station, heading towards Mirdif, the Auto Market and Al Warsan.

The Roads and Transport Authority (RTA), which runs Dubai's public transport, says the project is about 20% complete and expects to reach 30% by the end of 2026. The opening date remains 9 September 2029.

The line in numbers

  • Cost. More than AED 20.5 billion, about US$5.6 billion, awarded in December 2024 to a consortium of two Turkish firms, MAPA and Limak, and the Chinese rail company CRRC.
  • Length. 30 km, of which 15.5 km runs underground and 14.5 km on elevated track, including a 1.3 km bridge that will be the first metro crossing of Dubai Creek.
  • Stations. 14 in total: seven elevated, four underground and three interchanges with the existing network.
  • Riders. The RTA forecast about 200,000 passengers a day by 2030 and 320,000 by 2040, with trains roughly every two minutes.
  • People served. The districts along the route are planned to house around one million residents by 2040.

The districts it serves

The line has two branches that meet at International City 1, which will be the largest underground interchange in the network.

  • The longer branch, about 21 km with 10 stations, starts at Creek station on the Green Line in Al Jaddaf, crosses to Dubai Festival City and Dubai Creek Harbour, passes Ras Al Khor and continues through International City 1, 2 and 3 and Dubai Silicon Oasis to Dubai Academic City.
  • The shorter branch, about 9 km with 4 stations, runs from Centrepoint on the Red Line in Al Rashidiya through Mirdif and Al Warqaa to International City 1.

At Dubai Creek Harbour, the Emaar Properties station will stand 74 metres tall, which the RTA describes as the tallest metro station in the world. The RTA says the line will give residents along the route a direct connection to Dubai International Airport, with journeys of about 20 minutes, and reduce road congestion on the corridors it serves by around 20%.

How a metro line moves property values

A reliable rail connection widens the pool of people willing to live in an area, because the commute to the main business districts becomes shorter and more predictable. That tends to show up first in rents and then in prices. The RTA's own appraisal estimated that the Blue Line could raise property values near its stations by up to 25%.

Some of that is already visible. In June 2025 the brokerage Betterhomes, using Property Monitor data, reported that rents in Blue Line districts had risen an average of 23% since the route was announced in November 2023. Studio rents in Academic City were up 43%, Dubai Creek Harbour 30%, Al Warqa and Silicon Oasis 28%, International City 22%, and Mirdif and Festival City 15%. Brokers also point to the Red Line, which opened in 2009, as evidence that homes within a short walk of a station tend to outperform. These are market estimates from firms with an interest in the outcome, so they are best treated as a direction of travel rather than a forecast.

What to check before buying near the future line

  • Real walking distance. Measure the walk from the building entrance to the planned station, not the straight line on a map. A few hundred metres in summer heat makes a large difference to tenants.
  • How much is already priced in. Compare current rents and prices with similar areas that are not on the line. Part of the expected gain may already be reflected.
  • Timing. The line is due in late 2029. Plan for three more years of construction nearby and allow for the possibility of delays.
  • Elevated sections. Units facing an elevated track or station can suffer from noise or lost views, even while the building gains from access.
  • The basics still matter. Title, service charges, building quality and, for off plan purchases, the developer's delivery record count for more over time than proximity alone.

What it means if you are buying in Dubai

The Blue Line brings many of Dubai's more affordable districts within easy reach of the city's main employment centres, which is good news for owners and for buyers looking for value with long term demand behind it. It also fits well with residency through property. Since late April 2026, a sole owner of completed property in Dubai can apply for the two year property investor visa with no minimum property value, while joint owners need a share worth at least AED 400,000 each. Property with a combined registered value of AED 2,000,000 or more qualifies for the 10 year Golden Visa, which carries no minimum stay.

Before committing, check the title, the station plan, the developer and the realistic rent. Our real estate due diligence service covers these checks in the UAE through our local team, and our UAE residency service can then take care of the visa. We quote our fees in writing.
