Highways, Bridges & Tunnels

Trusted advice, deep expertise.

Bridge with road

Major investment is critical to the future of transportation infrastructure, creating opportunities for both the public and private sectors to plan for growing demand, maintaining and rebuilding aging infrastructure, integrating advanced technology, and helping the transition to sustainable operations and investments, prioritize decarbonization, and leverage green finance. 

As highway demand grows and existing infrastructure ages, there will be the need for the construction of new and rebuilding of existing roads, bridges, and tunnels. Also, as electric and autonomous vehicles reshape mobility, new types of infrastructure will be needed, while aging assets must be maintained and modernized. Evolving funding, financing, operational, and regulatory models will be essential to maximizing both social benefits and commercial returns from the development of this infrastructure. Public-private partnerships (PPPs) will play a key role in meeting global infrastructure needs at scale and speed.
