Vaal Aerotropolis developers seek environmental authorisation for first phase of R22.6bn airport project south of Johannesburg
Why It MattersA cargo-first greenfield airport would add freight and passenger capacity beyond Gauteng's existing airports, though the plan remains unapproved and construction is not scheduled before 2029.
Developers of the R22.6 billion Vaal Aerotropolis, which includes a new international airport and a planned smart city south of Johannesburg, are now seeking environmental authorisation for the project's first phase. The development is led by Vaal Aerozone in collaboration with government and development agencies and is planned for the proposed Vaal Special Economic Zone (SEZ) in the Emfuleni Local Municipality, about 9km west of Vanderbijlpark. It spans 13 farms across Heidelberg, Kookfontein, Langlaagte, Rietspruit and Zwartkopjies. According to the Sedibeng District Municipality, R12.2 billion of the total is allocated to the airport, which is expected to be Gauteng's first designed with integrated air cargo facilities as a priority.
Phase 1 would establish the airport's essential infrastructure: a passenger terminal able to handle 7.2 million travellers a year, a cargo terminal with a capacity of 150,000 tonnes of freight annually, a 4.2km runway designed for Code F aircraft, and two rapid-exit taxiways. It would also include aircraft parking, maintenance areas, fuel storage, road connections and municipal infrastructure such as water, electricity, wastewater treatment and stormwater systems. A planned airport city would include commercial offices, medical consulting facilities and a hotel with more than 90 rooms.
Construction of Phase 1 is scheduled for 2029 to 2031, with operations targeted for 2032, subject to approvals and the absence of unforeseen delays. Construction is expected to create about 12,000 jobs and the completed airport is projected to support 6,000 permanent positions. The wider SEZ is planned over 60 years in three phases, with airport capacity expanding in response to demand. The broader plan includes an agricultural zone with climate-controlled greenhouses, hydroponic farming, tissue culture facilities and perishable-export infrastructure, plus a trade zone for manufacturing warehouses and distribution centres. Key stakeholders include the Department of Trade, Industry and Competition (dtic), the Gauteng Growth and Development Agency (GGDA) and the Emfuleni, Lesedi and Midvaal municipalities. A central ambition is a green industrialisation hub focused on renewable energy and green hydrogen.
The proposed SEZ has been through government-led public consultation. In 2023, Citibank pledged R1.4 billion towards the first phase of the airport and aerotropolis. The project remains a development plan rather than an approved construction project, with environmental authorisation among the next critical milestones.
