Wonmunna Mine site intersection

Working directly for ASX 200 listed Mineral Resources, RDH delivered the intersection of the Wonmunna Mine site access road and the Great Northern Highway, approximately 90km north of Newman. With iron ore prices at all time highs, RDH worked closely with the client to ensure that the 24/7 ore road deliveries to Port Hedland were not compromised through the delivery of scope. To do this RDH provided 24/7 traffic control at the works sites, managing the ingress and egress of the quad road trains to and from the Great Northern Highway without affecting other road users in the area.

Works involved construction of a 2km acceleration lane, 900m passing lane and improved junction into the Wonmunna mine site from the Great Northern Highway at SLK 1250.90.
