On 17 November 2023 during a meeting between Bahrain’s King Hamad bin Isa al-Khalifa and Qatar’s Prime Minister Sheikh Mohammed bin Abdulrahman al-Thani, the plan for the bridge recommenced and they ordered administrations of both countries to realise the project.

As of June 2015, construction had not started, and the Qatar–Bahrain Causeway project was on hold, while the contracting consortium involved with the project was said to be demobilising, according to a source at the Qatar Bahrain Causeway Foundation (QBCF). On 14 January 2011,
Bahrain's Foreign Minister stated that the project should nevertheless be considered as a must for both countries: "This is one economic market, one economic zone that should be well-connected, and the bridge is an integral part of that". On 27 April 2011, an announcement was made, quoting an anonymous source of Bahrain's Al Wasat newspaper, that construction of the causeway would start in 2011 for completion in 2015, at the cost of approximately $5 billion. By December 2012, Bahrain's Foreign Minister was invoking financial turbulence to say that the bridge construction would only be completed by "a little before the

. Escalating costs and the subsequent diplomatic row helped place the project on the back burner.
In November 2023 the causeway project came back to life during a meeting in Manama between Qatar’s Prime Minister and Minister of Foreign Affairs Sheikh Mohammed bin Abdulrahman Al Thani and Bahrain’s Crown Prince.
On February 22, 2024, it has been announced that the proposed land border crossing between Bahrain and Qatar has received a fresh boost as officials from two sides have agreed to restructure the board of the project as part of its implementation.
This was discussed during the fourth meeting of the Bahrain-Qatari Follow-up Committee held in
