Joncet bypass: Reinforced Earth® walls stand tall

Terre Armée is involved in work on the RN 116 bypass in the village of Joncet, designing and supplying 6,200 m² of walls thanks to TerraTrel®.

The work, launched in 2013 and commissioned by the Languedoc-Roussillon and Midi-Pyrénées Regional Directorate for Environment, Land Planning and Housing (DREAL LRMP), was divided into two phases:

-        The first phase completed in 2014 involved restoration of the Chemin de Flassa, a forestry road to the north of the village, needed for the bypass to go ahead. Led by the Razel-Bec/Guintoli/GTS/Screg Consortium, the project required 1,600 m² of mineral TerraTrel® including on a true abutment supporting an engineering structure.

-        The second phase executed by the Guintoli/Razel-Bec/Colas Consortium is ongoing and involves construction of the bypass with 4,600 m² of mineral TerraTrel® laid on 3 Reinforced Earth® walls.

The work is expected to be completed in 2018 with the construction of a final wall, but Terre Armée can already be proud of the part it played in creating these remarkable 17-metre-high structures.

An eagerly awaited bypass

Welcomed with some relief by the inhabitants of this small village with houses blackened by pollution, this bypass project is the outcome of a battle that lasted several years. Dissected by the RN 116 trunk road, Joncet, a hamlet with around sixty inhabitants, saw on average 5,000 cars and trucks pass through each day and endured the corresponding noise and pollution.

Finally declared in the public interest in 2011, the bypass was approved with the plan to create a stretch of road around 1.5 kilometres long situated above the village and parallel to the existing RN 116. This solution will ultimately help preserve the hamlet, ensure the safety of its inhabitants and improve traffic flow between the Plaine du Roussillon and the mountain territories.
