Linear infrastructure

Linear infrastructure — roads, motorways, railway lines and road infrastructure — forms the backbone of everyday transport. In the face of climate change and evolving patterns of use, their design, maintenance and adaptation require high-level engineering that combines performance, resilience and environmental sustainability.

setec tpi designs, specifies and manages major linear infrastructure projects in France and internationally: high-speed rail lines (LGV), urban bypasses, motorways, junctions, associated landscaping, retaining structures and standard engineering structures.

The projects undertaken reflect a holistic approach, based on risk management, route optimisation, integration into the landscape, minimising environmental impacts and innovation aimed at decarbonising transport.
