Roads and Transport Upgrades

The City of Johannesburg’s Transport Department has prioritised the rehabilitation of key transport corridors. These connect major landmarks and summit venues. According to a March 2025 statement from city officials, over 150 kilometres of roadways are being resurfaced. The focus is on arterial routes like Rivonia Road and the M1 highway, which are crucial for accessing the Sandton Convention Centre and OR Tambo International Airport.

The City of Joburg is upgrading traffic signal systems with adaptive technology alongside road resurfacing. This system will ease congestion by dynamically adjusting signal timings based on real-time traffic flows. Officials are establishing dedicated lanes for summit convoys and coordinating traffic management plans with the Johannesburg Metro Police Department to ensure smooth transit during the event.

Utilities and Services Improvements

Utility providers City Power Johannesburg and Eskom have ramped up their infrastructure upgrade efforts. City Power has confirmed that more than 40 substations in high-demand areas have undergone capacity upgrades. Preventative maintenance is conducted to minimise outage risks. Eskom has reinforced the national grid supplying Johannesburg. They have implemented contingency backups and advanced monitoring systems to detect and address faults swiftly.

In terms of water supply, Johannesburg Water has reviewed the city’s waterworks. They are implementing pipeline repairs and boosting water pressure in vulnerable areas to ensure uninterrupted service. Telecommunications companies are also expanding fibre-optic infrastructure to enhance bandwidth. This effort ensures robust communication capabilities for the summit, especially for media coverage.

Public Spaces and Venue Enhancements

The Johannesburg Development Agency (JDA) has been tasked with upgrading public spaces critical to the summit experience. This includes refurbishing the Nasrec Expo Centre precinct, where the main summit sessions will take place. The upgrades involve installing energy-efficient LED lighting and upgrading HVAC systems to meet international air quality standards. They are also enhancing security access control systems.

Landscaping improvements are underway in parks and pedestrian zones across Sandton and the city’s central business district. Designers have installed new seating that prioritizes both comfort and aesthetics.Environmental sustainability is a key consideration. The upgrades incorporate solar-powered lighting and water-efficient irrigation systems to enhance sustainability and reduce environmental impact.

Accommodation and Hospitality Sector Readiness

Several hotels around Sandton have undertaken extensive renovations to align with international standards. They focus on security enhancements, upgrades to conference facilities, and hospitality staff training. The Gauteng Tourism Authority has worked closely with private sector partners. This ensures that accommodation capacities meet G20 standards. It also ensures that staff receive the necessary preparation to handle the influx of high-profile international guests confidently and professionally.

Safety and Security Measures

In collaboration with the South African Police Service, Johannesburg officials have expanded CCTV coverage around key summit venues and accommodation clusters. Emergency response teams have undergone specialised training to handle potential incidents swiftly. Officials have established a dedicated command centre to coordinate summit-related operations. It integrates intelligence, surveillance, and emergency communications for effective coordination during the event.

Environmental and Sustainability Initiatives

In line with the G20’s commitment to sustainable development, Johannesburg’s infrastructure projects prioritise “green” solutions. These include extensive tree planting in urban areas and the installation of energy-efficient fixtures in public buildings. Summit organisers have designed waste management strategies to ensure zero landfill contributions. A recent Gauteng provincial report also highlighted Johannesburg’s climate action strategy. It is a central element of the city’s preparations.

Community Engagement and Communication

Municipal authorities have been actively engaging with local residents, businesses, and transport users. Communication happens through town halls and digital platforms. These communications aim to minimise disruptions caused by construction, traffic rerouting, and service interruptions. At the same time, the city is highlighting the positive outcomes of the event, such as job creation and increased tourism opportunities.
