Présentation

• Castres est la plus grande sous-préfecture du département du Tarn et un important centre industriel. La ville est desservie par la RN112 depuis Mazamet, la RN126 depuis Toulouse (appelée à être transformée en autoroute), la D612 depuis Albi et quantité d'autres routes départementales.
• La rocade a été construite par étapes depuis la fin des années 1990, avec l'objectif de désenclaver toute l'aire urbaine de Castres-Mazamet. Les travaux restent inachevés mais Castres est désormais dotée d'une rocade semi-circulaire enserrant la ville par l'Ouest en raison d'un relief plus favorable et d'une convergence des principaux axes de circulation.
• La rocade est composée de 3 éléments :
  • Une voie express (15 km) ceinture largement l'agglomération par l'Ouest. Elle présente des caractéristiques hétérogènes : 2x2 voies au Nord de la RN126 et 2x1 voies au Sud de cet axe, même si un certain nombre d'ouvrages d'art ainsi que les emprises sont calibrées pour un doublement de la chaussée. Les échanges sont dénivelés sauf aux extrémités ainsi qu'au croisement avec la RN126 où un carrefour giratoire totalement superflu est implanté sur ce nœud à fort trafic.
  • Un premier boulevard urbain (2 km) relie la rocade à la D612 au Sud de Castres. Il a été mis en service en même temps que la voie express voisine et dessert plusieurs zones d'activités.
  • Un second boulevard urbain (5 km) ponctué de très nombreux giratoires relie la rocade à la D622 au Nord de Castres. En dépit de ses dimensions modestes, il facilite sensiblement l'accès à la Montagne de Lacaune.
• A l'avenir, il n'est pas prévu d'achever la boucle autour de Castres avec un maillon Ouest entre la D622 et la D612. De même, un doublement de la rocade Ouest n'est pas programmé, la priorité étant désormais de réaliser l'autoroute entre Toulouse et Castres (projet A69).
