Roads represent one of Colas’ long-standing core businesses.
Colas, your trusted partner in roadworks
Present in over 50 countries, the Group supports local authorities, infrastructure operators, and developers in the construction, modernization, and maintenance of their road networks, as well as in the development of public, residential, and industrial spaces. Its local roots and innovative capacity enable Colas to offer a comprehensive range of works, incorporating technical products and services designed in its own laboratories.
A broad range of business lines and expertise
Colas carries out road projects of all sizes, including major roads, highways, municipal roads, public transport systems, cycle paths, footpaths, etc.
We work hand-in-hand with local communities, taking into account specific uses, operating constraints, sustainability requirements, and user expectations.
Our road projects incorporate a range of factors including operational requirements, integration into urban or rural settings, and environmental impact control.
Our expertise on the ground serving the sustainable development of communities

Urban development projects, public transport, and active mobility
Colas delivers comprehensive urban development projects, combining roads, utility networks, and soft mobility, ensuring user comfort and safety.

- The regeneration of downtown areas and residential zones
- Dedicated public transport infrastructure: bus lanes, reserved lanes, BRT systems, stations, multi-modal hubs
- Footpaths, cycle paths, junction traffic calming, meeting areas
- Urban furniture, specific surfacing, the use of vegetation, and street lighting
A global vision of mobility and safety
Colas has expertise that complements its core business, enabling it to tackle road projects with an integrated approach to community development and functional mobility.
Signaling and safety
Through its subsidiary Aximum, Colas handles:
- Horizontal road markings and road signs
- Active (light-emitting signaling, dynamic road signs) and passive (safety barriers, restraint systems) safety installations
- Road and urban area equipment (street lighting, speed bumps, etc.)
Innovations for mobility
Colas also develops technological solutions, from smart signaling to traffic management systems.
- Flowell: interactive light-emitting marking for smart signaling
- Symphonie.Cam: smart traffic light solutions for shared and safe mobility
Responsible and innovative solutions
Colas designs and deploys differentiating technical solutions to adapt its operations to local constraints, contexts of use and reduced environmental and user impact objectives.
Customized technical support
Each project benefits from dedicated engineering, based on an analysis of the context, the expectations of the contracting client and the specific constraints associated with the work.
Colas provides experienced teams, tried and tested technical solutions, and appropriate management tools to ensure reliable and safe worksites.
Capacity to conduct complex and international road projects
Although a significant proportion of Colas' business is based on local contracts, the Group also mobilizes its expertise for large-scale road projects, characterized by their geographical scope, technical complexity, or contractual arrangements.
Colas thus undertakes projects within the framework of:
- complex contractual arrangements: concession, PPP (Public-Private Partnership), PFI (Private Finance Initiative), ASC (Asset Support Contract)
- joint enterprises or stakeholdings, often minority, in infrastructure concession companies.
These projects relate to major strategic roads, urban road systems, airport infrastructure, and urban public transport systems.
