According to the RCRC, this stage of development will include work on 14 main intersections, five tunnels, 33 bridges and six pedestrian bridges.
Once complete, the infrastructure is expected to support more than 950,000 vehicles daily.
The programme is part of Riyadh’s urban expansion efforts, aiming to address road congestion, increase overall network efficiency, and reinforce the city’s role as a centre for major global events.
The new projects will upgrade several specific roads. The southern section or the Sheikh Jaber Al-Sabah Road, which stretches 12km, will see the construction of six main intersections, 22 bridges, and three tunnels, providing capacity for 350,000 vehicles per day.
The central section or the Prince Turki bin Abdulaziz Al Awwal Road, covering 9km, includes three intersections, two tunnels and six bridges, with a projected daily capacity of 200,000 vehicles.
The 6km Prince Mishal bin Abdulaziz Road project includes two intersections, two bridges, and four pedestrian bridges, and is designed to carry up to 200,000 vehicles per day.
Meanwhile, 13km of Najmuddin Al-Ayoubi Road (western section) will be redeveloped, including three intersections, three bridges and two pedestrian bridges, to handle up to 200,000 vehicles per day.
The broader Main and Ring Road Axes Development Programme was launched by Saudi Arabia’s Prime Minister, Mohammed bin Salman bin Abdulaziz, who also chairs the board of the RCRC.
The overall initiative spans more than 500km of Riyadh’s road network and aims to upgrade existing routes, create new corridors and establish an integrated and efficient system by 2030.
According to the RCRC, the programme aims to cut travel times, improve everyday mobility, and enhance quality of life in line with Saudi Vision 2030.
