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.

Contractors submit prices for Upper Zakum expansion project16 March 2026

Contractors have submitted commercial proposals for the next expansion phase of the Upper Zakum offshore field development in Abu Dhabi, aimed at increasing the asset’s oil production potential to 1.5 million barrels a day (b/d).
The offshore oil and gas production business of Abu Dhabi National Oil Company (Adnoc Offshore) has divided the UZ 1.5MMBD project’s engineering, procurement and construction (EPC) scope of work into three packages, MEED previously reported.
Contractors submitted commercial bids for package 1 by the 23 February deadline and for packages 2 and 3 by the 27 February deadline, according to sources. The previous deadline for submission of commercial bids was 15 January.
Adnoc Offshore is understood to have issued the main tender for EPC works for the UZ 1.5MMBD project in the third quarter of last year.
Contractors submitted technical bids for package 1 by 21 November, while proposals for packages 2 and 3 were submitted by 14 November, MEED previously reported.
In November 2024, MEED reported that Adnoc Offshore had awarded a contract for front-end engineering and design (feed) and pre-feed services on the project to France-headquartered contractor Technip Energies.
A kick-off meeting between Adnoc Offshore and Technip Energies took place on 21 November 2024.
Located 84 kilometres offshore in Abu Dhabi, Upper Zakum is the world’s second-largest offshore oil field and fourth-largest oil field.
The UZ 1.5MMBD project is the latest crude output expansion undertaken by Adnoc Offshore at the Upper Zakum field development.
Upper Zakum expansion
The first phase of the programme to raise the Upper Zakum offshore field development’s oil production capacity to 1.2 million b/d was launched in 2019. The initial goal was to increase the field’s output potential to 1 million b/d by 2024, which was later increased to 1.2 million b/d, with the project execution timeline eventually extended.
In April last year, MEED reported that Adnoc Offshore had awarded the main EPC contract for the UZ 1.2MMBD EPC-1 project to UAE-based Target Engineering Construction Company. The value of the contract was estimated to be $825m.
The project’s main scope involved the EPC of several surface facilities and plants at the Upper Zakum offshore development’s four main artificial islands: Al-Ghallan, Umm Al-Anbar, Ettouk and Asseifiya – also known as Central Island, West Island, North Island and South Island, respectively.
Spanish contractor Tecnicas Reunidas won the contract for the feed works on the UZ 1.2MMBD EPC-1 project in 2019. UK-headquartered Wood Group was appointed as the project management consultant for the EPC phase.
In November 2024, MEED reported that Adnoc Offshore had also selected Target for the second phase of the Upper Zakum 1.2 million b/d project (UZ 1.2MMBD EPC-2). The value of the contract was estimated to be about $500m, according to sources.
Target began work on the project in December last year, MEED previously reported.
The scope of work on the UZ 1.2MMBD EPC-2 project covers the EPC of several structures on Assefiya Island.
Adnoc Offshore performed the feed work on the UZ 1.2MMBD EPC-2 project in-house.
Upper Zakum oil production
Adnoc Offshore has committed to a total capital expenditure budget of approximately $30bn, along with its operating partners in the Upper Zakum hydrocarbons concession, Japan Oil Development Company (Jodco) and US-based ExxonMobil.
The strategic objective is to first raise the asset’s oil output from 640,000 b/d to 750,000 b/d through the UZ 750 project, then to 1.2 million b/d through the two phases of the ongoing UZ 1.2MMBD project, and eventually to 1.5 million b/d.
Zakum Development Company (Zadco), which later merged into Adnoc Offshore, awarded EPC contracts for the UZ 750 project in 2012 and early 2013.
The $817m first package was awarded to a consortium of Abu Dhabi’s NMDC Energy (then known as National Petroleum Construction Company) and Technip Energies. Package two, the project’s largest EPC package, worth $3.7bn, was awarded to a consortium of UK-headquartered Petrofac and South Korea’s Daewoo Shipbuilding & Engineering.
EPC work on UZ 750 began in 2014 and was completed in 2022.
In October 2022, Adnoc Group subsidiary Adnoc Drilling set a world record for drilling the longest oil and gas well at the Upper Zakum concession, stretching 50,000 feet.
The extended-reach wells will tap into an undeveloped part of the Upper Zakum reservoir, potentially increasing the field’s production capacity by 15,000 b/d without expanding or building any new infrastructure, Adnoc said.

Neom cancels The Line tunnels contracts16 March 2026

Register for MEED’s 14-day trial access
Neom has cancelled the contracts related to the construction of the tunnel sections of The Line in northwest Saudi Arabia.
In a stock exchange announcement filed on 13 March, South Korean contractor Hyundai E&C said that Neom cancelled its contract on 29 December last year.
Hyundai E&C was executing the drill-and-blast section of The Line’s tunnels in a joint venture with Greece’s Archirodon and South Korean counterpart Samsung C&T.
The firm said its share of the joint venture was about 35%, amounting to $483m.
Neom awarded contracts for constructing the mountain tunnel sections of The Line in June 2022.
The drill-and-blast works were split into four packages, with two contracting teams winning two packages each.
The other joint-venture team comprised Spain’s FCC, the local Shibh Al-Jazira Contracting Company (Sajco) and Beijing-based China State Construction Engineering Corporation.
The tunnels formed part of the infrastructure backbone of Neom’s 170-kilometre The Line development, launched in January 2021.
What began as Crown Prince Mohammed Bin Salman’s defining symbol of a post-oil Saudi Arabia unravelled with quiet finality over roughly two years. By April 2024, planners were reportedly being forced to cut the initial phase to just 2.4km by 2030.
By July last year, with the sovereign wealth fund facing tightening liquidity, the kingdom was reported to have conducted a “strategic review” to determine whether The Line was feasible – a process described as a “recalibration” of Vision 2030.
Resources are now being directed to projects essential for the Fifa World Cup 2034, Expo 2030, and critical housing, healthcare and education targets.
According to media reports, the government has pivoted towards repositioning what remains of Neom as an industrial and data centre hub, leveraging the Red Sea coastline’s access to seawater cooling for artificial intelligence (AI) infrastructure.

Bidders get more time for Riyadh East sewage treatment plant16 March 2026

State water offtaker Sharakat, formerly Saudi Water Partnership Company (SWPC), has extended the bid submission deadline for the Riyadh East independent sewage treatment plant (ISTP).
The new deadline is 30 June. The original deadline was 2 April.
The project will be developed under a build‑own‑operate‑transfer (BOOT) model with a 25‑year concession term.
The plant will have a treatment capacity of 200,000 cubic metres a day (cm/d) in its first phase, expanding to 500,000 cm/d in the second phase.
It includes the development of a treated sewage effluent transmission pipeline, forming part of the kingdom’s wider programme to expand wastewater treatment capacity through public-private partnerships.
The request for proposals (RFP) was issued last October.
In 2024, Sharakat prequalified 53 companies that could bid for the Riyadh East ISTP, part of seven planned ISTP projects it said it would procure between 2024 and 2026
WSP is the technical adviser and KPMG Middle East is the lead and financial adviser on the project.
The targeted commercial operation date for the facility is 2029.
ISTP plans
Sharakat’s current ISTP portfolio includes 10 large plants that are operational, under construction or under tendering, with a combined initial treatment capacity of 1.79 million cm/d.
These projects include North Taif, Jeddah Airport, West Dammam, Madinah 3, Buraydah 2, Tabuk 2, Al-Haer, Arana, Hadda and Riyadh East.
In December, two consortiums were selected for contracts to develop and operate the Hadda and Arana ISTP projects in Mecca province.
That same month, Sharakat prequalified 63 developers for upcoming ISTP projects under a revised prequalification process.
According to Sharakat’s newly released seven-year statement, it has identified six additional large ISTPs in the development pipeline.
These include:
- Kharj (75,000 cm/d)
- Abu Arish (50,000)
- Hafar Al-Batin (100,000)
- Riyadh North (TBD)
- Najran South (50,000)
- Khamis Mushait (50,000)
The company is also pursuing a nationwide small sewage treatment plant programme covering about 139 smaller ISTPs grouped into seven clusters.
These are designed to add roughly 521,450 cm/d of additional treatment capacity across the kingdom.

Modon launches Tara Park on Abu Dhabi’s Reem Island16 March 2026
Abu Dhabi-based Modon Holding has launched the Tara Park residential project in the Reem Island area.
The project comprises two residential towers with a total of 340 residential units.
The development includes a 527-metre jogging track.
The latest project launch follows Modon Holding’s launch of the Bashayer residential waterfront community on Hudayriyat Island.
The project will comprise 157 four- and five-bedroom villas centred around a clubhouse with a rooftop infinity pool, and 330 one- to four-bedroom apartments across two low-rise buildings.
The development comprises a 3.5-kilometre waterfront promenade and a park.
In October last year, Modon Holding launched the Maysan residential development on Abu Dhabi’s Reem Island.
This development covers an area of about 600,000 square metres.
Maysan is being developed in several phases. The project’s first phase involves developing two districts: Mayar and Thoraya.
The first district, Mayar, consists of 132 mansions. The four-storey mansions will be located within a gated community featuring a central park and walking trails.
The second district, Thoraya, features 184 townhouses. It will include gardens, play areas, a gym and other associated facilities.

Jordan begins prequalification for Amman water project16 March 2026
Jordan’s Ministry of Investment has issued a request for qualifications (RFQ) for a non-revenue water (NRW) reduction project in the southern and southeastern areas of Amman.
The project will be delivered under a public-private partnership (PPP) model using a design, build, finance, operate and maintain structure. It aims to reduce water losses and improve the efficiency of water distribution networks in the targeted areas.
The initiative is being led by the Ministry of Investment through its PPP unit in collaboration with the Ministry of Water & Irrigation, the Water Authority of Jordan and Miyahuna.
The procurement is expected to attract international water operators, engineering contractors and infrastructure investors with experience in NRW reduction programmes.
The bid submission deadline is 23 April.
Jordan has prioritised reducing NRW as part of efforts to improve the efficiency of its water sector. The country is among the most water-scarce in the world, and losses from distribution networks are estimated to account for about 45% of water supplied.
NRW reduction programmes typically involve measures such as network rehabilitation, leak detection, pressure management and improved metering to reduce physical and commercial losses across water systems.
Jordan is also advancing its $6bn Aqaba-Amman water desalination and conveyance project that aims to meet about 40% of Jordan’s municipal water demand by 2040.
As MEED recently reported, the project is nearing financial close. Once complete, it will supply about 300 million cubic metres of potable water a year from the Red Sea to Amman and other regions.
In February, the Water Authority of Jordan signed a four-year performance-based management contract with France’s Veolia to support water and wastewater services in the country’s northern governorates.
Under the contract, Veolia will provide operations, maintenance and management services to Yarmouk Water Company, the public utility responsible for water supply and wastewater services in the region.
