Nesma wins $311mn transport contract for Diriyah Interchange – Construction Week Online

Diriyah Development Company (DevCo), a subsidiary of Saudi Arabia’s Diriyah Gate Development Authority (DGDA), recently awarded a SAR1.2bn ($311mn) contract to one of Saudi Arabia’s largest industrial and engineering companies, 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 Arabian capital’s arterial motorway system.

The tunnels will form part of a 2.1km long, one-way, 4-6 lane revolving road system underneath Diriyah Square, essentially a mega subterranean roundabout to facilitate intuitive, easy vehicle access and egress from Diriyah.
