Since January 2014, within the new high speed railway bypass Nîmes-Montpellier, Oc’Via Construction has been constructing the viaduct Lez-Lironde in Lattes.
This project with a length of 576 m consists of a 90 m viaduct.
The metallic structure includes two side arches on which the hangers, delivered by La GTM France, are fixed. These hangers in grade S355NL have an outer diameter of 180 mm for lengths between 3.2 and 14 meters [no coupler \ in one piece!]
The hangers with a cold threaded rod end support the deck (slab) of the construction. The set consists of the pier reinforced concrete and two viaducts, in concrete and with steel, allows crossing three successive lines (the Lez River, the Georges-Frêche Avenue and the Lironde River).
The project was finished by the end of 2015.
