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.

What actually slows a gigaproject down9 September 2026

Ask anyone delivering a major programme in the GCC what causes delays and sequencing will come up early. Utilities go in too late. Approvals lag behind construction. Stations, depots and access roads are procured as if they belong to different projects rather than one system.
“None of this is new. The industry has understood these risks for years,” says Alan Caldwell, managing director for transport and infrastructure at WSP Middle East.
For Caldwell, that is what makes the pattern worth interrogating rather than simply restating.
“The more important question is why the same issues around interfaces, approvals, stakeholder alignment and delivery sequencing continue to slow major programmes when the risks are already so well understood,” he says.
The answer, he argues, is not that these programmes are too big or too technically complex. What breaks a schedule is a wider system delivered as a set of disconnected parts; an approval sitting with an authority team with no visibility of the construction sequence downstream; or a station package proceeding without the utilities diversion it depends on.
“Infrastructure programmes do not struggle because a railway is too large or a highway network is too complex,” Caldwell says. “They encounter difficulties when interconnected elements are delivered in the wrong order.”
Sequencing decisions are rarely purely technical either, he adds. They are commercial – shaped by which assets need to unlock value first, which phases are tied to funding, and where sales or investment assumptions depend on infrastructure landing in a particular order.
Approvals sit at the centre of that logic. On many programmes, they become one of the biggest sources of lost time – not because the requirements are unreasonable, but because approvals are not planned, evidenced or owned as part of the delivery logic from day one.
Caldwell has seen the same pattern across three decades of Gulf delivery, from early work on Palm Jumeirah to today’s region-wide transport programmes.
“The decisive factor has often been the same: whether interfaces, approvals, responsibilities and delivery sequencing are aligned early enough to prevent complexity becoming delay.”
Integration needs to be well understood
“Most programme teams in the region would say they understand the need for integration,” Caldwell says. Fewer are structured to deliver it. “The harder task is turning that understanding into the way projects are actually set up and managed,” he argues.
Riyadh Metro is the reference point he returns to, precisely because engineering complexity was not the deciding factor in its delivery.
Coordinating a city-scale transport system meant aligning design, construction, systems, utilities and stakeholder interfaces across every delivery vertical.
“The lesson for the region today is clear,” Caldwell says. “Ambitious programmes need a delivery model that gives every contributor a shared view of progress, risk, decision-making and the business case driving programme priorities.”
That shared view, he argues, will be what the next phase of Gulf delivery is judged on.
Whether clients, consultants, contractors, operators and approval authorities can work to a single delivery logic will be key.
“This requires more than coordination meetings. It requires integrated ways of working, shared common data environments and governance structures that make risks, decisions and dependencies visible before they become delays,” he says.
From reporting progress to managing risk before it lands
Digital tools have a role here, Caldwell says, but not as a headline in themselves.
Digital twins, programme visualisation and data-led modelling matter only if they help teams identify and address problems before they affect the wider programme.
“The real value is not technology for its own sake,” he says. “It is the ability to see, in one place, where approvals are outstanding, where interfaces are unresolved, where programme dates are slipping, where clashes are emerging and where decisions need to be escalated."
None of it works without governance behind it, he cautions. “A dashboard will not resolve a delayed approval if nobody knows who owns the decision, when it needs to be made, or how it should be escalated.”
Data only has value if the processes and responsibilities around it are clear, which is why Caldwell frames the shift the region needs not as digitisation, but as a move “from programme management as a discipline focused mainly on reporting and coordination, and towards project and programme intelligence”.
With many of the region’s programmes running for a decade or more, he adds, delivery models also need to flex as funding assumptions, user needs and policy priorities change along the way.
“The ambition behind the Gulf’s transformation programmes is not in question,” Caldwell says.
What will determine how much of it is realised on time is whether delivery models evolve at the same pace: earlier integration, clearer approval pathways, shared data environments, and every contributor working to a delivery logic that connects technical sequencing with the funding and operational case behind it.
“The region’s next challenge is not imagining bigger projects,” he says. “It is changing the way they are delivered, operated and adapted over time.”

Jordan tenders advisory for wastewater treatment plant9 September 2026
The Water Authority Jordan (WAJ) has issued an invitation to prequalify for advisory services for the rehabilitation and expansion of the Shallala wastewater treatment plant in Irbid, northern Jordan.
The Shallala plant was commissioned in 2013 with a design capacity of about 14,000 cubic metres a day (cm/d).
The rehabilitation and expansion project will increase its treatment capacity to about 30,500 cm/d to meet projected wastewater flows through 2050.
The PIU Support and Construction Supervision Consultancy Services tender was released on 19 August.
The submission deadline is 21 September.
The consultancy will support the project implementation unit and provide construction supervision services for the project. The project has an estimated value of $69m and is being financed by the European Bank for Reconstruction and Development.
The planned works include rehabilitating the existing activated sludge and treatment units and constructing a new treatment train.
The scope also includes installing biogas combined heat and power units, improving sludge handling and dewatering systems, and installing odour control and chemical containment systems.
WAJ is also undertaking the upgrade and expansion of the Ain Ghazal wastewater treatment plant in Amman.
The existing facility had a capacity of 330,000 cm/d and is being upgraded to 726,712 cm/d to accept and treat expected incoming flows until 2045.
The local Arab Towers Contracting Company was appointed as the main contractor for the project last year.

Medina’s KEC signs real estate project development deal9 September 2026
Medina’s Knowledge Economic City (KEC) has signed an agreement with Riyadh-based Kaden Investment Company to develop a mixed-use project in Medina.
The project will have an estimated gross floor area of about 230,000 square metres (sq m).
According to a statement filed by KEC with the Saudi Exchange (Tadawul), the project – called Multaqa Al-Madinah 2 – will be built on a 92,000 sq m plot located directly north of the first phase of the Multaqa Al-Madinah development.
It is expected to include about 1,527 residential units across three residential zones, along with commercial and office space totalling about 31,108 sq m of net leasable area.
It will also feature parking, recreational and service facilities, landscaping and other supporting infrastructure.
KEC and Kaden intend to deliver the project through a closed-ended real estate investment fund regulated by Saudi Arabia’s Capital Market Authority.
Under the proposed structure, KEC will contribute the land as an in-kind contribution and hold 75% of the fund units, while Kaden will contribute cash and hold the remaining 25%.
Kaden will also serve as the development manager.
KEC said the land has been initially valued at about SR692.3m ($184.6m), while the total equity required for the project is estimated at around SR833m.
Once final agreements are signed, KEC expects to receive SR67.7m in cash and fund units valued at approximately SR624.6m.

Iraq solar package on track to come online in December9 September 2026

The 1,000MW solar photovoltaic project in Artawi – also called Ratawi – in southern Iraq is on track for its second phase to come online on 8 December, according to industry sources.
This phase has a capacity of 250MW and will bring the project’s total online capacity to 500MW.
The first phase of the project, also with a capacity of 250MW, came online in March this year.
The third and fourth phases, each with a capacity of 250MW, are expected to be brought online next year.
The solar project is part of the broader Gas Growth Integrated Project (GGIP), which has an estimated total value of $27bn and a first phase worth an estimated $10bn.
The solar project’s ownership differs from the headline GGIP ownership structure, with its ownership equally divided between France’s TotalEnergies and QatarEnergy.
The wider GGIP consortium includes TotalEnergies, Iraq’s Basra Oil Company and QatarEnergy, which hold stakes of 45%, 30% and 25%, respectively.
China Energy Engineering Corporation is part of a consortium that is executing the main engineering, procurement and construction contract for the project.
It announced that the first 250MW of capacity had been connected to the grid on 4 March this year.
The consortium also includes China Energy Engineering Group Tianjin Electric Power Construction Company and Chengdu-headquartered Southwest Electric Power Design Institute Company.
The project scope includes:
- Construction of a substation
- Installation of a 132kV booster station
- Installation of solar panels
- Installation of transformers
- Laying of transmission lines
- Construction of related infrastructure
In February 2025, Basra Investment Commission director Alaa Abdul Hussein said the solar plant had an estimated total value of $820m.
The GGIP programme is focused on developing four major projects in Iraq:
- The Common Seawater Supply Project (CSSP)
- The Ratawi gas processing complex
- The 1GW solar power project for Iraq’s electricity ministry
- A field development project at Ratawi, known as the Associated Gas Upstream Project (AGUP)
All four of these projects are currently under execution, though there have been some delays related to the regional war that started when the US and Israel attacked Iran on 28 February.
The conflict has caused significant disruption to shipping through the Strait of Hormuz, which Iraq uses to export crude oil and import equipment and materials for projects.
