Highways

Increasing resilience in road networks.

Highway network operators face multiple competing priorities, including maintenance to keep roads safe for users and investment to enhance capacity and increase connectivity between communities.  

Population growth, urbanization, and changing travel habits are placing a strain on our road networks. With higher temperatures and more intense storms becoming more frequent, the resilience of our road infrastructure is under extreme pressure. 

A systematic approach to operating and managing assets is essential to tackle this, making full use of existing and emerging digital technology. Enhancing and renewing the network should be done in a collaborative environment, gaining public and stakeholder support by maximizing social, environmental, and economic value while delivering with certainty of schedule and cost.

What can we do for you?

We work with policymakers, government agencies, road agencies and authorities, statutory and regulatory bodies, private owners and operators, and other stakeholder groups to plan, design, and deliver a wide range of highway projects and programs.

We can help you:

Explore a collaborative and innovative approach

We create solutions that fit the specific needs and context of the most complex challenges, deploying innovation and a breadth of specialist expertise to develop projects that work for all road users.

Implement data-driven asset management

We can help make sense of data to prioritize the necessary interventions and focus investment where it is most needed across the road network.

Cut carbon

From strategic advice to on-the-ground know-how, we are market leaders in reducing carbon in highways projects. We are also coauthors of PAS 2080, the international specification for managing infrastructure carbon.  

Deliver excellent value

We retain a focus on value for money at every stage of a project, with significant expertise in contractual assurance, schedule certainty, and risk mitigation, while still delivering transformative client outcomes. 

Services we provide

Smart highway design for efficient transportation

We have a multidisciplinary skill set, and work across the entire lifecycle of highways projects. We use our broad technical expertise, analytical thinking and collaborative problem-solving approach to give you an end-to-end service and deliver well-designed, efficient, and sustainable roads and assets.

Our experience

Our heritage in the highways sector stretches over a century, when we were involved in major UK projects such as the Tyne Bridge in the 1920s. Today, we work on complex projects in North America, Australasia, the Middle East and Asia as well as UK and Europe.

Some highlights of our recent work include:

  • A303, Somerset, UK
    As part of a joint venture with Sweco, we provided design services to help develop this new 5 km section of dual highway to alleviate congestion between Sparkford and Podimore on this trunk road in Somerset. We were involved in this nationally significant infrastructure project from options identification and assessment through development consent order submission and examination.
  • Area 10 asset support, UK
    In a joint venture with Balfour Beatty and on behalf of Highways England, we helped operate 570 km of strategic road network covering Merseyside, Cheshire, Lancashire, and Greater Manchester. Under a contract that ran between 2012 and 2019, we carried out asset management, renewals and network enhancement — including 24/7 incident response — to ensure safe operation.
  • Lower Thames Crossing, UK
    We’re part of a joint venture working for National Highways to deliver this new 23 km road and tunnel linking Essex and Kent, which is planned to relieve pressure on the M25 and Dartford Crossing; we’re working with Skanska on designing and building the Kent section of the project south of the River Thames.
  • National Highways net zero plan, UK
    As part of a consortium of partners, we helped National Highways form a plan to achieve net zero by 2050, encompassing corporate, supply chain, and road user emissions, and also to achieve accreditation to PAS 2080, the international standard for the management of infrastructure carbon. National Highways was the first highway owner-operator in the world to achieve this standard.
  • North-South Corridor, Singapore
    Our involvement in this major road tunnel in Singapore — which connects the north and south of Singapore beneath the city center — dates back to the original feasibility study in 2008. We’re now providing design services to the consortium of contractors delivering the project, including detailed design for five of the ten project sections.
  • North Union Street Transformation, New York, USA
    The city of Olean set out to convert the four-lane car-oriented commercial district of North Union Street to a two-lane “complete street" that would revitalize the neighborhood. Our design encourages pedestrian and bicycle use, calms traffic, and spurs economic activity.
  • Rome-Cartersville development corridor, Georgia, USA
    We’re acting as design consultant to the Georgia Department of Transportation in developing the plans for this four-lane, 9 km road linking the US411 and I-75 highways, with construction due to start in 2026.
  • Torrens Road to River Torrens, Adelaide, Australia
    Working closely with the South Australian Department of Planning, Transport and Infrastructure, we provided design services for this complex 4 km section of highway that provides a vital link in the North-South Corridor, one of Adelaide’s primary road transportation routes.

Carbon Portal

Identify, calculate, and reduce embodied and operational carbon emissions. This infrastructure carbon calculator is aligned to PAS 2080, the international specification for managing carbon across the built environment (coauthored by Mott MacDonald). It allows anyone across your business and supply chain to identify and calculate carbon emissions, not just carbon experts.

Ash Dieback

Our Ash Dieback solution scans verges using vehicle mounted cameras. Then, trained to identify unhealthy trees, it maps and digitally tags them for felling. The process is many times faster than traditional surveys reliant on human observation; it is also more accurate and much safer.

Traffic Management

Traffic Management is a monitoring and control system that improves traffic managers’ ability to respond to incidents and changing road conditions, improving safety and reducing congestion.
