We work with our clients to manage complex tunnel systems, provide dedicated 24/7 Incident Response services and manage and maintain tunnel facilities, internal structures, ventilation and fire systems in a safe and reliable way.

DM Roads is employed to carry out the maintenance of Australia’s longest tunnel, the North Connex in Sydney, providing day to day operation support as well Incident Response teams who are on stand-by to respond to any vehicle breakdown or incident in the tunnel.

On NorthConnex we deliver the majority of reactive, routine, cyclical and planned maintenance with our own directly employed teams from the local area. Our proven track record shows that this approach gives us the best control over safety, quality and service resilience. 

Our supply chain partners are an extension of DM Roads during all important shutdown maintenance. We work collaboratively to inspect, assess and maintain the tunnel to minimise downtime for the benefit if the traveling public.

We are proud of the opportunity to work with our client Transurban to develop employees and create wider opportunities for trainees, apprentices and Aboriginal and Torres Strait Islander employment.   

In 2021, NorthConnex also received a global excellence award from the International Association of Lighting Designers for the in-tunnel lighting design. This award recognises all the research, partnerships, and work involved to create and maintain a unique experience for road users.
