Diriyah Gate Development Authority achieved a milestone in its Gyratory Tunnel Extension project by setting a new record for concrete pouring. This initiative is part of a broader effort to enhance the infrastructure surrounding the historic Diriyah area, a UNESCO World Heritage site in Saudi Arabia. The successful pour of 1,600 cubic metres of concrete in a single stretch underscores the project’s ambitious scale and the authority’s commitment to modern engineering standards.

This concrete pouring feat not only demonstrates the technical capabilities involved but also highlights the strategic importance of the project’s timeline. The Gyratory Tunnel Extension is integral to the anticipated urban development, which aims to facilitate improved traffic flow and accessibility to Diriyah, thus boosting tourism and economic activity in the region. The development is expected to bolster the area’s attractiveness as a cultural and historical destination.

Located to the west of capital Riyadh and 25km from King Khalid International Airport, the DG II Gyratory Tunnel Extension is a 700-m-long extension to the original road tunnel from the gyratory system beneath the Diriyah Square development. The project is being implemented by the Diriyah Gate Development Authority.
