Traffic drives construction underground

3 April 2025

 

On 14 February, Dubai construction was thrust again onto the global stage when Elon Musk, the world’s richest man, announced plans to explore the development of an underground Dubai Loop transportation system, along the lines of the Las Vegas Convention Centre Loop project in the US.

Dubai has typically made headlines globally by constructing the world’s tallest towers. As the city becomes increasingly congested on the surface, it is taking some of its largest construction projects underground.

With Musk’s backing, the Dubai Loop scheme is the most high-profile tunnelling project launched to date. It involves carving a futuristic transport system underneath Dubai. The initial phase of the project is currently being studied by Dubai’s Roads & Transport Authority (RTA) in partnership with The Boring Company, which is owned by Musk. It will cover 17 kilometres (km) and have 11 stations, with the capacity to transport over 20,000 passengers an hour.

The project highlights the importance of expanding underground infrastructure in the Middle East region. This is mostly necessitated by the pressure that rapidly growing cities have put on existing transport and utility networks, particularly in major urban centres such as Dubai, Riyadh and Doha.

Underground opportunities

Projects that involve tunnelling, such as metro rail systems, underground highways and pedestrian walkways, are deemed key enablers in reducing congestion and optimising land use.

The recently completed metro systems in Riyadh and Doha are examples of how underground rail networks can facilitate efficient urban mobility, and more such schemes are planned. 

Without these subterranean projects, cities risk being stuck in a permanent state of gridlock, with longer commute times and decreased productivity. At the same time, tunnelling allows urban planners to integrate sustainable transport solutions, as well as large-scale utilities networks, without disturbing existing cityscapes, thereby enhancing connectivity and economic growth.

These developments signal a major shift in engineering priorities, with regional governments investing in underground transport, sewerage and metro extensions to accommodate their growing populations and infrastructure needs.

While the tower crane-dotted skylines of urban centres in the GCC attract attention, delivering major projects underground is an equally impressive engineering feat. Tunnelling under busy cities requires advanced excavation techniques, careful planning and coordination to avoid disruptions.

More tunnelling work is expected as Dubai takes another significant step forward in tackling its ongoing traffic problems [with] a new metro link

UAE tunnelling projects

Tunnelling work forms a significant portion of the Dubai Metro Blue Line extension. Awarded in December for AED20.5bn ($5.5bn), the project includes 15.5km of underground track and five subterranean stations. When operational in 2029, the Blue Line will significantly expand Dubai’s metro capacity, linking major residential and commercial hubs.

More tunnelling work is expected as Dubai takes another significant step forward in tackling its ongoing traffic problems by starting the procurement process for its next metro link: the Gold Line.

Although the technical details of the project have yet to be revealed, it is expected that tunnels will form a major component of the scheme given that the new line will run through busy urban areas where there is little space to build overground. 

The Gold Line will start at Al-Ghubaiba in Bur Dubai. It will run parallel to – and alleviate pressure on – the existing Red Line, before heading inland to Business Bay, Meydan, Global Village and residential developments in Dubailand.

As a first step, the RTA has sent a request for proposals to companies for the lead consultancy role on the multibillion-dollar project.

The UAE’s Etihad Rail also began a study of the tunnels required for the high-speed railway line connecting Abu Dhabi and Dubai in January. The survey works are ongoing on the Jaddaf and Dusup tunnels that will serve the high-speed rail link. Initial plans for the project include tunnelling works totalling 31km.

Another major tunnelling project in the UAE is the $22bn Dubai Strategic Sewerage Tunnels scheme. The client, Dubai Municipality, is preparing to tender its first packages, which include deep tunnels that will stretch 42km in Jebel Ali and 16km in Warsan.

The project will be delivered under a public-private partnership model, with international consortiums competing for contracts. Once completed, these tunnels will replace the traditional wastewater network, reducing energy consumption and enhancing long-term sustainability.

Saudi schemes

In Saudi Arabia, Riyadh is preparing to expand its metro network with the addition of a Line 7 and an extension to the existing Line 2.

The total length of Line 7 will be about 65km, of which 47km will be underground. The line will have 19 stations, 14 of which will be underground.

The project involves constructing a metro line linking the Qiddiya entertainment city development, King Abdullah International Gardens, King Salman Park, Misk City and Diriyah Gate. 

In March, the Royal Commission for Riyadh City (RCRC) gave consortiums until 15 June to submit their bids for a design-and-build contract for the construction of Line 7.

The planned Line 2 extension is 8.4km long, of which 7.1km is underground, and three out of its five stations will be built underground. The RCRC is expected to award the construction contract this year.

In January, the kingdom also completed the phased roll-out of the Riyadh Metro network. The current network comprises six lines spanning about 176km, of which 74km is constructed underground.

These numbers indicate that over 42% of the overall network is underground, highlighting the growing importance of tunnels in the kingdom’s plans to improve infrastructure in its most densely populated cities.

Tunnelling works are also a key component of the plans to improve the stormwater drainage system in Jeddah, where the municipality is preparing for the construction of the King Abdullah Road-Falasteen Road tunnel.

The three-year scheme involves constructing 5.3km of tunnels with an internal diameter of 7.2 metres using tunnel boring machines (TBMs) and another 3.4km of tunnels with a diameter of 3.5 metres driven by pipe jacking or TBMs.

At the kingdom’s Neom gigaproject, city planners are looking to find solutions to many of the problems faced in existing cities and, as a result, tunnels and large-scale underground utilities corridors are being built at the beginning of the project. For example, the development’s Delta Junction tunnels will serve as a railway junction connecting the Spine infrastructure corridor with the Neom Connector rail link to the Oxagon industrial zone. 

The project involves 26.5km of tunnelling work that will be split into a north and a south lot. The construction works are expected to begin this year as the client is evaluating the revised proposals submitted by firms in November last year.

Kuwait Metro will feature extensive tunnelling … ensuring minimal disruption to existing roads while integrating with future transport networks

Further tunnel projects

Beyond the Gulf, Egypt has a long history of tunnelling projects, as it has had to deal with crippling congestion and urban overcrowding for decades. In the 1980s, work was completed on two major projects that involved tunnelling: the first phase of the Cairo Metro system and the Greater Cairo wastewater project, which involved the construction of sewage tunnels on the east and west banks of the Nile. 

Today, Cairo’s tunnelling projects include the Cairo Metro Line 4 project. Spanning 42km with 39 stations, it involves over 20km of tunnels.

Meanwhile, in Morocco, national railway operator L’Office National des Chemins de Fer (ONCF) is constructing a tunnel project in Rabat.

In February, ONCF announced a 3.3km tunnel to be constructed under the Bou Regreg river at an estimated cost of MD1.4bn ($140m). The tunnel will connect the Sale and Agdal stations in an effort to alleviate traffic.

Similarly, the long-awaited Kuwait Metro will feature extensive tunnelling to navigate the dense urban fabric of Kuwait City, ensuring minimal disruption to existing roads while integrating with future transport networks. 

Qatar’s expansion of Doha Metro, meanwhile, requires additional underground infrastructure to connect developing areas and support the country’s vision for a comprehensive public transport system. 

Mecca Metro, already serving millions of pilgrims, is also set for further expansion, likely involving significant tunnelling to facilitate smoother access to holy sites while overcoming geographic constraints. 

In Oman, the Muscat Metro project is likewise expected to link key districts while preserving the city’s landscape and avoiding disruptions to arterial roads by introducing underground sections. 

All of these projects show that tunnels will play an important role in the region’s future as it strives to create cities with more efficient and environmentally sustainable transit and utilities systems.

  • UAE moves to clear the path for recovery

    17 June 2026

    Commentary
    Colin Foreman
    Editor

    More than three months after the conflict began to disrupt business across the Gulf, the UAE is moving to resolve the technical challenges that the economy faces as it shifts towards recovery.

    The insurance gap has been a key obstacle to the recovery of aviation and tourism. Several countries continue to maintain advisories against travel to the Gulf, making it difficult or impossible for visitors to obtain conventional cover for trips to or through the region. The concern is twofold: one, becoming stranded should hostilities resume, and two, not being able to secure medical insurance. Both Emirates and Etihad have now moved to address that directly, offering insurance to passengers flying to or through their respective home hubs. The Etihad scheme, backed by DCT Abu Dhabi and underwritten by Daman, will run from July to December and covers eligible visitors for up to 15 days.

    The second area of concern is real estate. Anecdotally, buyers in sectors economically exposed to the conflict have found it increasingly difficult to obtain mortgage financing, a problem that has become especially acute at the point of handover. The recently signed partnership between Dubai Holding Real Estate and Commercial Bank of Dubai is designed to ease that pressure. The programme opens financing from the 30% construction stage once buyers have met a 50% payment threshold, giving purchasers earlier visibility of their borrowing capacity and reducing uncertainty during the off-plan purchase process.

    Taken together, the two initiatives show that the UAE is proactively addressing the technical hurdles as and when they arise. As the recovery gathers momentum, more challenges will surface. The capacity and willingness to address them as they emerge will be crucial to a meaningful recovery.

  • Libya signs three oil deals after licensing round

    17 June 2026

    Libya’s National Oil Corporation (NOC) has signed three production-sharing agreements with several international energy companies following the country’s first licensing round in nearly two decades.

    The three agreements have been signed with the following consortiums:

    • Block O1 – offshore – Eni (Italy; 60%) and QatarEnergy (40%)
    • Block O7 – offshore – Repsol (Spain; 40%), Turkiye Petrolleri A O (TPAO; Turkiye; 40%) and MOL Group (Hungary; 20%)
    • Block C3 – onshore – Repsol and TPAO

    The contracts are three of the five announced as awarded in February this year as part of the 2025 licensing round.

    The three contracts were signed on 15 June.

    It is not known why the remaining two awarded contracts have not been signed.

    The remaining two contracts are:

    • Block M1 – onshore – Aiteo (Nigeria)
    • Block S4 – onshore – Chevron (US)

    Libya is seeking to attract investment and raise oil production capacity to 2 million barrels a day (b/d) from around 1.4 million b/d currently.

    The chairman of NOC, Massoud Suleman, said that the agreements reflected growing confidence in Libya’s oil and gas sector and would support exploration, development and production growth.

    The 2025 licensing round was Libya’s first licensing round since 2007.

  • US–Iran deal sets Hormuz road map

    17 June 2026

    Register for MEED’s 14-day trial access 

    The US-Iran agreement, declared complete on 14 June, reopens the Strait of Hormuz, lifts the US naval blockade and ends a war that has closed the Gulf’s export artery since 28 February. The strait reopens at Friday’s signing on paper, but the recovery will take months.

    US President Donald Trump announced the deal on Truth Social, authorising the "toll-free opening" of the strait and the immediate removal of the blockade, with formal signing set for Geneva on 19 June – with vice-president JD Vance to sign for Washington and parliamentary speaker Mohammad Baqer Ghalibaf for Tehran in the highest-level US-Iran meeting since 1979.

    Iran’s deputy foreign minister Kazem Gharibabadi confirmed the text was finalised but said Tehran would not implement it until signing, with the strait staying closed in the interim.

    Signing versus substance

    The signing on 19 June is merely the starting line that will set in motion a partial reopening to traffic alongside a clearance operation to remove the mines laid by Tehran across key sections of the strait.

    The memorandum gives Iranian forces 30 days from signing to clear the strait of mines. At the same time, the Pentagon’s estimates appear to suggest that a full minesweeping could take up to six months, even with three dedicated vessels in the region.

    Such gaps – here a 30-day treaty obligation against a six-month operational reality – have become the running feature of the bilateral negotiations, which have been framed by mutual distrust and plagued by an absence of granular detail.

    The deal is welcome for the region despite its uncertainty. Behind the mines sits a tanker backlog built over more than 100 days, and Gulf producers that throttled back production and need time and assurances to restore flow.

    Before the war, roughly 100 ships transited daily; Kpler now projects around 40 a day could sail within the first month, but with an estimated 300 loaded vessels stranded on either side of the strait, and 250 more sitting empty and idle in the Gulf, it is a pressure release valve, not an immediate restoration of flow.

    A total restoration of oil and trade flows is unlikely to come into view before the year’s end.

    Insurance represents the second brake, with war-risk premiums standing at 1-4% of vessel value per transit, or about $8m for a $200m tanker – against less than 0.1% before the war.

    Shipping associations are no less cautious, with the Baltic and International Maritime Council calling for verified mine-free routes before volume traffic resumes.

    Insurance underwriters are likewise unlikely to relent on prices until clearance is confirmed.

    Conditional relief

    Markets have already traded the sentiment, however. Brent settled at $87.33 on 13 June – an eight-week low – and have fallen further as the deal has firmed. As of early morning trading on 16 June, the first full day of trading after the Islamic New Year, Brent was down at $78.

    Yet the relief remains highly conditional: a 60-day nuclear negotiation now follows the signing, and a breakdown in either this, passage through the strait or peace in Lebanon could return the strait to crisis.

    The US-touted toll-free terminology is also narrower than billed, with the Iranians instead affirming a 60-day grace period for fees but not eliminating the possibility of “fees” for navigation, environmental and insurance services after that point.

    The distinction is legal, not rhetorical, with international maritime law barring tolls on passage through natural straits but permitting the imposition of service fees on vessels passing through territorial waters.

    It is through this terminology that Iran is now consistently framing its plans to charge fees from passing vessels through the office of its Persian Gulf Strait Authority – established 5 May and since sanctioned by the US Treasury.

    For the Gulf, a 60-day waiver that resolves into an Iranian (and possibly joint Omani) fee regime is a pause in Iran’s tollgate economy, not its end – and would represent a strategic concession for the US, the Gulf and the globe.

    Levant entanglement

    Lebanon is another conditional space that the deal cannot fully escape, with a flare-up on that front being the final potential trigger that could collapse the 60-day agreement.

    Iran has explicitly tied a ceasefire in Lebanon to the resolution of transit in the strait, but Israel does not agree with this, and the linkage may have inadvertently handed Tel Aviv the exact tool it needs to disrupt the US–Iran ceasefire – through the simple of continuing a conflict that it already wants to continue.

    Within a day of the deal, Israeli Defence Minister Israel Katz said the IDF would stay in southern Lebanon “without any time limit”, with US officials corroborating that Israeli withdrawal was never a condition of a deal.

    On the ground, the ceasefire is already looking frail, with post-deal fire straying in both directions and already endangering the regional calm and Hormuz reopening the Gulf is already pricing.

    For Gulf producers and shippers, the distinction and in some cases friction between what the deal declares and what it actually delivers remains a cause for uncertainty.

    A declaration is easy, but the delivery requires nuclear negotiation, mine-clearance verification, insurance repricing and a 60-day political test before barrels can again move at volume.

    Trump, who has been frustrated for months with the slow progress on Iran from a US perspective, is also more than likely to be distracted by other concerns on a timeline shorter than 60 days – risking the political will to peace coming up short.

    In the Gulf, whether Saudi Arabia and the UAE send cabinet-level representatives to Geneva on Friday will signal whether the region’s political leaders are willing to wield the political capital necessary to keep the US on track and pursue the ceasefire to fruition.
