In 2017, a new high-speed line will optimize the serving of Brittany and Pays de la Loire.
In charge of this major project of linear infrastructure, Eiffage pledged alongside RFF in an exceptional sustainable development by its size, its diversity and cross.
In early 2011, RFF (France Ferrés Networks) held Eiffage for the construction of the future LGV Bretagne and Pays de la Loire, 182 km long infrastructure and falling in line to Rennes and Nantes Atlantic LGV Paris- Le Mans commissioned in 1989. the line will improve connections to the two regions, including the respective time savings of 37 minutes and 22 minutes between Paris and Rennes and Paris and Laval. The project includes the point of Sable-sur-Sarthe 3.6 km- -on which develop rail links within and between regions significantly reducing journey times between Angers and Nantes, Rennes and Laval.
Preparatory work started in July 2012, was followed in December 2012 by the first projects earthworks and civil engineering. The line should be completed in late 2016, for commissioning in the spring of 2017.
The site is divided into seven lots of TOARC (earthworks, structures, restoration of communications). More than two hundred art works are provided, including ten viaducts.

- The creation of 220 hectares of woodland and 280 ha of wetlands, including 81 pools of immediate compensation.
- The restoration of all streams and creating multiple passages adapted to allow wildlife to reduce the barrier effect of the line;
- The operations schedules are tailored to the biological cycles of many species;
- Sensitive or ecologically significant zones are marked in pen or near the site and within the ROW;
- amphibians, dependent on three types of environments: wetlands for breeding, and forest and hedgerow environments for wintering and feeding grounds;
- saproxylic insects (including the Spike Plum Osmoderma eremita and Great Capricorn Cerambyxcerdo), dependent on hedgerow habitats and forest environments;
- bats occupying various ecological niches between their hunting area and various lodgings (hibernation, mating, transit, calving).

- Follow and to compare the environmental variables over a sufficiently long period (10 full years between 2012 and 2022) to be considered representative.
- Beyond a simple regulatory balance sheet, it is to advance the science and enrich knowledge in the environmental field.
- Among the topics considered observation: landscape evolution, the study of hedgerow network, monitoring of amphibian populations ...

The record of state commitments provides an Environmental Observatory of the establishment to assess the project's impacts on the environment. It aims to enrich the knowledge and practices to reduce environmental impacts and to provide useful feedback for future infrastructure projects.
This observatory is a shared initiative between the work of masters SNCF Network and Eiffage Rail Express (ERE) and with DREAL (Regional Directorates of Environment, Planning and Housing). These actors constitute the operational management of the observatory. The steering committee meets meanwhile all the partners involved in the project with colleges (and socio-economics) chaired by the prefects of Brittany and Pays de la Loire.
The aim of the observatory is twofold:
The Observatory is also working on the study of socio-economic data, with thematic observation the effects of construction on employment, attractiveness and territorial dynamics.
