Nesma secures Diriyah Interchange contract
01 March 2022
Diriyah Gate Development Authority (DGDA) said one of its subsidiaries, Diriyah Development Company (DevCo), has awarded a SR1.2-billion ($311 million) contract to a leading Saudi company, Nesma & Partners, to construct a network of road tunnels, ramps and a major bridge deck that will form the principal Diriyah Interchange on Riyadh’s Western Ring Road (WRR).
The WRR will provide seamless traffic access and egress between all Diriyah Gate zones and the Saudi capital’s arterial motorway system, said the DGDA.
The tunnels will form part of a 2.1-km long, one-way, four- to six-lane road system beneath Diriyah Square, essentially a mega subterranean roundabout to facilitate intuitive, easy vehicle access and egress from Diriyah, it stated.
The major bridge deck spanning across the WRR will also support Heroes’ Park, an iconic public gathering space for people, central to Diriyah’s masterplan, it added.
The main elements of the contract works are the demolition of two existing motorway bridges, the relocation of major public utilities, 1.5 million cu m of rock excavation, the construction of a network of road tunnels, ramps and a major bridge structure, incorporating 350,000 cu m of concrete and 60,000 tonnes of steel reinforcement, said the DGDA.
At its peak, more than 1,800 people will be working on the construction site, it added.
Diriyah Gate is the mixed-use part of the giga-project, with history and heritage assets at its core, enriched by entertainment, shopping, hospitality and residential elements. Diriyah and its Unesco World Heritage Site of At-Turaif, is known for its large adobe structures, built in the Najdi architectural style native to the region.
Group CEO Jerry Inzerillo said: “Our vision for Diriyah Square is a beautiful, pedestrianised mixed-use space that prioritises walkability for locals and visitors. This forthcoming tunnel connection to the gigantic underground car park and the Heroes’ Park Deck is essential to realising this vision. Its construction will create approximately 2,500 jobs, significantly contributing to the kingdom’s goals for Vision 2030.”
