Road & Highway Design

From delivering the SA Government’s first design and construct road project in the 90s to operating in five states, we deliver specialised road and highway design services to our clients across the country.

Having undertaken the design of several key road infrastructure projects around Australian over many decades, Tonkin understands the  importance of balancing road design criteria & standards with safety and
cost outcomes to ensure a value for money solution is achieved for our clients.

Our team of engineers and road designers bring a collaborative approach to projects, from concept through to detailed design development. We work closely with clients to highlight requirements, risks and opportunities, ensuring the competing demands on our road network are considered and managed to deliver reliable outcomes for all road users.

How vehicles use our roads is evolving and will continue to change as innovations addressing accessibility, mobility and road safety are developed. Tonkin is committed to helping our clients ensure road design solutions delivered now do not linit the development of future technologies and road uses.
