Road Infrastructure

Our dynamic team of professional traffic engineers, transport planners and road designers has built a reputation for delivering tailored solutions to unique and challenging projects from feasibility studies and concept planning through to detailed design, construction supervision and safety audits.

In a country as vast as ours, we are acutely aware as to how critical road infrastructure is to the shape of the economy and the welfare of motorists and pedestrians on the roads every single day. Keeping Australians safe and trucks moving requires keen focus on risk mitigation and due diligence. Lambert & Rehbein’s experienced engineers and designers are committed to the delivery of small to large road infrastructure projects safely, within budget, on time and entirely to specification.
