RCRC: New Bridge and Tunnel at Al-Thumamah–Sheikh Hassan bin Hussein Intersection

The Royal Commission for Riyadh City (RCRC) is upgrading the eastern section of Al-Thumamah Road to improve traffic flow and increase capacity along one of the capital’s key traffic corridors. Construction is underway on a 920-meter concrete bridge and a 1,600-meter tunnel at the intersection with Sheikh Hassan bin Hussein bin Ali Road to ease congestion and improve connections between surrounding neighborhoods.

A temporary traffic diversion took effect at the intersection on November 13, 2026, redirecting vehicles onto a road running parallel to Al-Thumamah Road. Alternative routes and directional signs are also in place to keep traffic moving and ensure motorists’ safety throughout construction. The arrangements are being implemented under a traffic management plan coordinated with the relevant authorities.

The works are part of the 8-kilometer eastern Al-Thumamah Road development project, which falls under Group Three of the Main & Ring Road Axes Development Program. The project includes three bridges and three tunnels and, once complete, will increase the road’s capacity to 200,000 vehicles per day, easing congestion and reducing travel times and delays.

The Main & Ring Road Axes Development Program aims to improve traffic flow across Riyadh and develop an integrated, sustainable urban transport network. Spanning more than 500 kilometers of roads across the capital, the program combines the construction of new routes with upgrades to existing major corridors and improved connections between them.
