The region’s most ambitious causeway projects
8 February 2023

The submission of feedback questionnaires and meetings with contractors for the planned second causeway connecting Saudi Arabia and Bahrain is the latest sign of potential progress on one of the region’s largest infrastructure projects.
Causeways have a chequered history in the region. The first causeway connecting Saudi Arabia and Bahrain was completed during the 1980s, and since then, it has had a transformative impact on the Bahraini economy.
The project’s success has inspired other causeways. But while these schemes remain ambitions for many in the region, construction progress has been limited. The hope is that a successful second causeway linking Saudi Arabia and Bahrain will foster the delivery of other longstanding causeway plans.
These are the most ambitious causeway schemes that the region has planned:
| Second Saudi Arabia-Bahrain causeway |
The second causeway between Saudi Arabia and Bahrain is the most likely to proceed. Planned by the King Fahd Causeway Authority, the $3.5bn project, which has been called the King Hamad Causeway project, is moving towards construction.
In 2021, senior government officials in Bahrain told MEED that the project was progressing towards tendering as financial studies had been completed.
The project was included in Bahrain’s $30bn Strategic Projects Plan that was announced later in 2021. As well as the causeway, the plan includes building new urban areas on five reclaimed islands to increase the country’s total land area by 60 per cent. It also comprises plans for a new airport.
The second causeway involves building a 25-kilometre road and rail crossing linking Saudi Arabia and Bahrain. It will follow the same alignment as the existing King Fahd Causeway.
It has been earmarked for delivery on a public-private partnership (PPP) basis. The King Fahd Causeway Authority appointed a consortium to provide transaction advisory services in late 2019.
The $8.9m consultancy agreement was signed with a consortium of Netherlands-headquartered KPMG, US-based Aecom and UK-based CMS. The team was tasked with working on developing the financing model, the required engineering specifications and design, as well as helping with the assessment and selection of the project’s developers.
Canada-based SNC Lavalin and UK-based consultancy firm PwC conducted the project due diligence study in 2017.
The existing King Fahd Causeway is operating at capacity. About 11.5 million cars cross the causeway every year, and the growth has been 6 per cent per annum over the past 10 years.

| Qatar-Bahrain causeway |
There have also been suggestions that the proposed causeway bridging Bahrain and Qatar may be revived. In March 2022, Manama called for work to restart on the causeway joining the two countries.
“We in the Kingdom of Bahrain renew the call for the start of bilateral talks between the two sides in accordance with the mechanisms agreed upon in the Al-Ula statement,” said Bahrain’s undersecretary for land transportation and post in an official statement published by the official Bahrain News Agency.
The estimated $4bn Qatar-Bahrain causeway project was put on hold and the contracting consortium demobilised in 2010.
A joint venture of state-owned developer Qatari Diar Real Estate Investment Company and French contractor Vinci Construction Grand Projets led the consortium. The other consortium members were Germany’s Hochtief, Athens-based Consolidated Contractors Company (CCC), Dredging International from Belgium and the local Middle East Dredging Company (Medco).
The planned 40km bridge includes a four-lane motor crossing scheduled for completion in 2013 and two railway lines forming part of the GCC rail network.
The project also comprises 22km of bridges and viaducts, 18km of embankments and two 400-metre cable-stayed bridges. The causeway connects Ras Ashairij on the west coast of Qatar to Askar on the east coast of Bahrain.
The project was also known as the Friendship Bridge and was to be jointly funded by the Qatari and Bahraini governments, which intended to recover some of the construction costs by implementing a toll system on the bridge.
The crossing would cut the journey time between the two countries, which currently involves a detour through Saudi Arabia, from five hours to just 30 minutes.
| Saudi Arabia-Egypt causeway |
The prospects for the causeway connecting the $500bn Neom project in Saudi Arabia and Egypt’s Sinai Peninsula across the Straits of Tiran improved last year after US President Joe Biden’s visit to Saudi Arabia.
After the visit, a joint communique issued by Washington and Riyadh referred to the development of Tiran Island.
“President Biden welcomed the arrangements by Saudi Arabia to remove the Multinational Force & Observers (MFO) from the Island of Tiran, including the removal of US troops there as part of the MFO mission, while preserving and continuing all existing commitments and procedures in the area,” it said.
“This area of the Red Sea will now be developed for tourism and economic purposes, contributing to a more secure, peaceful and prosperous region.”
The US-Egyptian-Israeli-backed MFO was founded in 1981 to oversee the terms of the 1978 Camp David Accords, which included the full Israeli withdrawal from the Sinai Peninsula.
In 2016, Egypt and Saudi Arabia agreed during a state visit to Cairo by King Salman bin Abdulaziz al-Saud to develop a causeway linking the two countries across the Red Sea.
The agreement was made as part of a broader deal that would also involve Egypt ceding the sovereignty of the two Tiran islands to Saudi Arabia.
While details of the proposed crossing were never revealed at the time, it was understood to be a revival of a $4bn project announced in 2011. That scheme involved building a 32km crossing stretching over the Straits of Tiran from Ras Humaid in Tabuk, in the northern region of Saudi Arabia, to Ras Nasrani, close to the Egyptian resort of Sharm el-Sheikh.
Plans to link Saudi Arabia and Egypt are far from new. The development of a causeway was first mooted as far back as 1988. However, the idea has received additional focus in recent years following the launch of the Neom development in northwestern Saudi Arabia, which includes Ras Humaid. Part of the Neom scheme, the 170km-long linear city known as The Line, will extend from the promontory inland to the city of Tabuk.
UK-based Arup was reported to have been selected in 2019 for the next stage of the feasibility study for the causeway.
Saudi Arabia was understood to be considering using a public-private partnership (PPP) model for the scheme, similar to other transport projects planned in and around the kingdom.
| Yemen-Djibouti causeway |
A 28.5km causeway was planned to connect Yemen and Djibouti before the scheme was put on hold in 2010 until the governments of both countries signed the framework agreement for the project. The civil war in Yemen means it is unlikely the scheme will make any progress soon.
The estimated $20bn first phase involved building the link between the Yemeni mainland to the island of Perim in the Red Sea. Phase two would have then connected Perim with Djibouti.
The wider project also involves building two cities at each end of the link. The total investment required to construct the cities and the bridge is $200bn.
Dubai-based Al-Noor Holding Investment Company was developing the project.
In 2009, the company said it expected to award a build-operate-transfer contract for the first phase of the bridge and that three companies had expressed interest in funding and building the road and rail link. Denmark’s Cowi prepared the preliminary design for the crossing.
| UAE-Qatar causeway |
In 2005, Abu Dhabi and Doha were reported to have been setting up a joint company to oversee the implementation of the proposed UAE/Qatar causeway.
The 40km causeway was expected to start near Sila in Abu Dhabi emirate and extend to the south of Doha.
The estimated $13bn crossing would have significantly cut journey times. At present, traffic between Qatar and the UAE has to pass through 125km of Saudi Arabian territory.
The scheme stalled shortly afterwards. Problems included difficulties with the route, which ran through Saudi Arabian territorial waters.

UAE monitors desalination plants after oil spill3 November 2026
State utility Etihad Water & Electricity (EtihadWE) says it is monitoring seawater quality at desalination plant intake points following an oil spill off the UAE's northern coast.
In a statement, the utility said it is continuing to "implement proactive measures to safeguard the water production system" following the spread of an oil slick towards coastal areas in the emirates of Umm Al-Quwain, Ras Al-Khaimah, Ajman and Sharjah.
The spill involved the tanker Gem No. 2, which was struck by a projectile in UAE territorial waters on 9 October. The resulting oil pollution has raised concerns over potential contamination of seawater used by desalination plants along the northern coast.
EtihadWE said its measures include continuous monitoring of seawater quality at plant intake points, regular testing of produced and distributed water, and verification of compliance with approved standards before water enters the distribution network.
The utility added that the precautionary measures will not affect the continuity of water supplies to consumers in the Northern Emirates.
In an earlier update on 30 October, the Climate Change & Environment Ministry said the oil slick was concentrated off the coast of Umm Al-Quwain, extending partially towards coastal areas in Ras Al-Khaimah, Ajman and Sharjah.
The ministry said the concentration of pollution had declined significantly and that the leak had been stopped at source. However, surveying, monitoring and clean-up operations are continuing in affected coastal areas.
The Energy & Infrastructure Ministry said specialised technical teams are continuing work to address technical issues with the tanker, including repairing damaged sections, restoring operational systems and assessing the integrity of its structure.
The proximity of the oil slick to the Naqa'a desalination plant in Umm Al-Quwain has drawn particular attention. According to media reports, the slick approached to within approximately 2 kilometres of the facility.
Naqa'a has a production capacity of 150 million imperial gallons a day, equivalent to approximately 682,000 cubic metres a day. The plant supplies water to the Northern Emirates and has been operational since 2022.
It is owned by Naqa'a Desalination Plant, a special-purpose vehicle established by Mubadala, Acwa and the former Federal Electricity & Water Authority, now known as EtihadWE.

Oman signs 1GW battery storage agreement3 November 2026
Oman's Nama Holding, a subsidiary of Oman Investment Authority (OIA), has signed a framework agreement with China's State Grid International Development to develop battery energy storage systems (bess) with a targeted capacity of 1GW.
The agreement covers two battery storage systems, each with a capacity of 500MW, at Duqm Industrial Station and Al-Subaikhi (Ibri Solar 3) Station.
It is understood that both systems will operate at 400kV and connect to Oman's national electricity transmission grid.
The deal is part of a package of economic and investment agreements signed by OIA with Chinese institutions and companies during the Oman-China conference on 2 November. OIA put the combined value of the bess projects at approximately RO384.5m ($1bn).
The agreement comes as Oman advances plans to expand its renewable energy capacity and strengthen the electricity transmission network.
Nama Power & Water Procurement Company is also procuring a separate 950MW standalone bess programme comprising five facilities in the sultanate, as MEED exclusively reported.
The wider package of agreements, signed during Sultan Haitham Bin Tariq's state visit to China, covers sectors including renewable energy, mining, logistics, digital transformation and space technology.
In the wind energy sector, Oman's O-Green and Shanghai Electric Wind Power signed a strategic partnership to establish a joint research and development centre and wind turbine testing facility at the Mawarid turbine factory in Duqm.
The partnership will focus on adapting turbine technologies to Gulf climate conditions, supporting local manufacturing and developing green ammonia projects in Oman.
The partnership is valued at RO3.85m-RO7.69m ($10m-$20m). It also identifies potential future contracts exceeding $1bn, alongside green ammonia projects and initial investment commitments in Oman exceeding $200m.
In solar, OIA signed a preliminary term sheet with Chinese firms PCG Power and Hoymiles for a partnership valued at RO38.45m ($100m).
The partnership aims to develop solar energy projects in Oman and establish a solar inverter manufacturing facility serving markets in the Middle East and North Africa.
It is also intended to support the localisation of solar-related industries, expand domestic production and develop export markets.

Consultants bid for Roshn’s north Riyadh scheme3 November 2026

Saudi gigaproject developer Roshn Group has received proposals from lead design consultants for its planned flagship development in north Riyadh.
Consultants submitted proposals on 1 November for detailed design, tender documentation and construction documents for the project’s first plot.
The planned development covers 13.7 square kilometres and will be a residential-led mixed-use scheme containing retail, office, hospitality, education and civic facilities.
The consultancy scope for plot one includes infrastructure, utilities, public-realm works and the site adaptation of Roshn’s residential prototypes. It has been divided into two work packages.
The first package covers phases A, B and E, which cover about 7.8 million square metres (sq m) and will include 17,000 units.
The second package covers phases C and D, covering about 4.7 million sq m and with more than 15,000 units.
The site is bordered by the Expo 2030 site, King Abdulaziz Park, the Sports Innovation Lab Zone and National Housing Company’s Khozam development.
Transport connectivity is a key element of the masterplan. Two metro stations are planned, including a station at the interchange between the existing Line 4 and planned Line 7, and a dedicated Line 7 station. The development could also be served by the planned Qiddiya high-speed rail link and a potential diversion of King Salman Road.
The scheme will add to Roshn’s existing development pipeline in Riyadh, which includes the multi-phase Sedra community. The developer is expanding its focus from single-family housing to larger mixed-use districts under its Roshn 3.0 strategy.
Last month, Roshn signed a preliminary agreement with TMG Saudi, the local subsidiary of Egypt’s Talaat Moustafa Group, to establish a joint venture to explore a separate mixed-use project in Riyadh.
TMG Saudi will hold a 51% stake in the proposed joint venture and Roshn will hold the remaining 49%. The companies said they will undertake detailed masterplanning and prepare a business case for the project, which preliminary studies indicate could include more than 55,000 residential units.

Adnoc awards contract for Ruwais Diyab unconventional gas3 November 2026

Abu Dhabi National Oil Company (Adnoc) has taken the final investment decision (FID) for the Ruwais Diyab unconventional gas development in Abu Dhabi.
The project will deliver 345 million standard cubic feet a day (scf/d) of raw gas from 2029 over a 25-year period, with the potential to reach up to 1 billion scf/d in the future.
Gas will be processed on site and connected to the UAE’s gas network through new pipeline infrastructure, “strengthening domestic supply, supporting the nation’s economic and industrial growth as well as Adnoc’s liquefied natural gas export ambitions”, the Abu Dhabi energy giant said when announcing FID on the project at the Abu Dhabi International Petroleum Exhibition and Conference (Adipec) 2026.
According to sources, Adnoc has awarded the design, build and operate (DBO) contract for the Ruwais Diyab unconventional gas development to China-based Jereh Group.
A formal kick-off meeting between Adnoc and Jereh is expected to take place later in November, sources told MEED.
The DBO contract awarded by Adnoc to Jereh is understood to cover the second phase of the Ruwais Diyab unconventional gas development. The tendering exercise for the project started last year.
“The development [of Ruwais Diyab] follows a disciplined programme of technical studies, field testing and subsurface analysis, delivered by Adnoc Onshore under a DBO model, to reduce development risk,” Adnoc said in its statement on 2 November.
“It brings together advanced subsurface expertise, artificial intelligence-enabled drilling and completion technologies and integrated project delivery capabilities to support the efficient and responsible development of domestic gas resources,” it added.
The UAE holds the seventh-largest gas reserves in the world, with 298 trillion standard cubic feet (scf) of conventional gas reserves and 160 trillion scf of unconventional gas resources.
Adnoc holds the majority 60% stake in the Ruwais Diyab concession, the majority of which is situated onshore, while France’s TotalEnergies holds the other 40% interest.
The agreement to explore, appraise and develop the area’s unconventional gas resources was signed by Adnoc and TotalEnergies in November 2018. The partners announced first gas output at the concession, presumably on a pilot basis, two years later.
Adnoc has set a target of producing 1 billion scf/d of gas from the Ruwais Diyab concession by 2030, in line with its target to achieve self-sufficiency in overall gas production by the end of this decade.
“Ruwais Diyab’s additional unconventional gas supply will strengthen Adnoc’s gas value chain, including Adnoc Gas’s ability to meet rising domestic and international customer demand,” Adnoc said in its 2 November statement.
“Ruwais Diyab advances Adnoc’s ambition to establish a scalable unconventional gas business and create a platform for future growth,” the company added.
Ruwais Diyab first phase
Adnoc awarded the contract for engineering, procurement and construction (EPC) on the first phase of the unconventional gas development programme to local contractor Astra Engineering & Construction in early 2025, according to regional project tracker MEED Projects.
The first phase aims to achieve a gas output level of 100 million scf/d. The main structures to be built in the first phase include a central processing facility, two well pads, interconnecting well fluid pipelines, gas export pipelines and tie-in stations.
The EPC contractor will be required to provide services such as surveying, design, engineering, procurement, expediting, transportation, fabrication, construction, testing, installation, pre-commissioning, commissioning, site performance testing, operation and maintenance of all units.
The duration of the EPC works is understood to be 20 months, with the contractor also responsible for operating and maintaining the phase one facilities for 15 years.

Sultan Al-Jaber appeals for global energy security reset2 November 2026
The global energy industry must fundamentally rethink how it builds, protects and delivers secure energy, following a year of unprecedented disruption that has exposed critical vulnerabilities in international supply chains, Sultan Ahmed Al-Jaber, the UAE’s Industry & Advanced Technology Minister and managing director and group CEO of Abu Dhabi National Oil Company (Adnoc Group) has said.
Delivering the opening address at the Abu Dhabi International Petroleum Exhibition and Conference (Adipec) 2026 on 2 November, Al-Jaber said preparedness is essential to navigating an increasingly uncertain global landscape.
“For decades, energy security was a question for specialists. It was debated in rooms like this, by people like us, in a language that few needed to learn. This year, every family, every farmer, every industry and every business owner is asking about it, and our collective job is to find the answers.”
Noting that it is not possible to control every situation and remove every risk, Al-Jaber said: “The choices we make today will determine the energy landscape a decade from now. Let’s apply the lessons we have learnt. Let’s build capacity and everything that supports it. Let’s forge partnerships that hold when it matters. And if you want a partner you can count on, you are in the right room, in the right city, in the right country. Because when it counts the most, you can count on the UAE.”
Setting out the case for a more resilient energy system, Al-Jaber said that since the disruption in the Strait of Hormuz, nearly 1 billion barrels of crude have been drained from inventories. He noted that in some markets, stocks of diesel are at their lowest seasonal level in 35 years, while others are facing a supply gap for liquefied natural gas (LNG) of 600 billion cubic feet. “Simply put, the world has eroded its supply buffers,” Al-Jaber said.
“But supply is only half the story. The other half is delivery. Before the disruption, logistics were less than 5% of the cost of a barrel. Today, they are more than 30%. In short, energy security is not only measured at the point of production. It is now also measured at the point of delivery.”
Mitigation steps
Al-Jaber outlined five steps the energy industry can take to reduce the impact of future shocks. “First, accessible supply. We need expanded strategic storage, larger stockpiles of products and flexible refining capacity closer to consumer markets.
“Second, routes to market. Supply only counts when it arrives. Infrastructure must be built before it is needed and enabled by advanced logistics.
“Third, operational intelligence. Moving from automated operations to intelligent energy systems that anticipate risk, optimise performance and drive down the cost of every barrel.
“Fourth, capital follows confidence. Policy must create it, finance must accelerate it and insurance must keep trade moving.
“Fifth, which is in my view the most important, is people. Because behind every barrel that arrives is a person who made sure it did. Systems don’t carry responsibility, people do.”
