Roads, bridges & tunnels

Trusted advice, deep expertise.

Bridge with road

Major investment is vital to the future of transport infrastructure, with opportunities for public and private sectors to plan for increasing demand, integrate advanced technology, shift to sustainable operations, prioritise decarbonisation and leverage green finance. 

As electric and autonomous vehicles reshape mobility, new infrastructure will be needed, while ageing assets must be maintained and renewed. Evolving funding, financing, operating, and regulatory models are key to maximising social benefits and commercial returns. Public-private partnerships will play a crucial role in meeting global infrastructure demands at scale and pace. 

We are the largest global advisory team for transport infrastructure investment, helping governments, sponsors, investors, operators, and lenders worldwide. We prepare robust traffic and revenue forecasts, deliver technical due diligence, implement sustainable strategies, and advise on financial structuring and business planning — supporting throughout the full lifecycle of an asset. 

Our expertise 

  • Traffic & revenue forecasting – Providing robust analysis to support investment, policy, and planning decisions. 
  • Technical due diligence – Assessing risk, feasibility, and opportunities to optimise project outcomes. 
  • Sustainable infrastructure & green finance – Advising on funding and financing models that prioritise decarbonisation. 
  • Public-Private Partnerships (PPPs) – Structuring successful collaborations to accelerate infrastructure investment. 
  • Asset management & lifecycle planning – Helping clients plan for maintenance, renewal, and long-term value.
