The concession plan for the A63 motorway in Les Landes is focused on improving the existing road. Converted into 2 x 2-lane road in the 1970-1980s, this obsolete infrastructure was starting to present some problems:
- A high accident rate, despite improvements already made
- A very high proportion of HGV traffic (30%), with no overtaking and a speed limit of 80 kmph
- Inadequate rest areas and services: insufficient storage capacity, few services
- Very damaged road surfaces
- A monotonous route conducive to sleepiness
- An obvious barrier affecting large animals and aquatic mammals
- Significant noise pollution for local residents, in the absence of noise processing devices
- This feedback concerns the widening of a 105 km section into 2 x 3 lanes, an improvement in the quality of service for users and the environmental quality of the infrastructure, and the preparation
of operating teams. The working environment, under operation, was particularly demanding.
Egis has contributed at several levels to this flagship project for the Aquitaine Region.
- In the shareholding of Atlandes, as the concession company;
- Within the engineering group responsible for the overall design of the project; and for the design, supply and installation of fixed operating equipment;
- Providing environmental support to Atlandes;
- As the operator, via Egis Exploitation Aquitaine.
