## Histoire:

À l'origine, la section Rivières-Pélissier, appartenait à l'ancienne ligne de 60 KV Saint-Sulpice-Pélissier construite en 1926. Une autre section entre Brens et Rivières appartenait à l'ancienne ligne de 60 KV Lisle-sur-Tarn-Pélissier construite elle aussi en 1926. C'est en 1950 que la ligne fut fracturée et raccordée au barrage de Brens dont les travaux avaient débutés en 1948. En 1951, la tension de la ligne électrique passe de 60 à 63 KV. En 1965, cette ligne a été fracturée et raccordée à Gaillac.

Entre 1983 et 1984, lors de la restructuration du réseau électrique du Tarn, et la mise en service du réseau à 225 KV, la ligne fut prolongée jusqu'à Albi via une section de l'ancienne ligne de 63 KV Saint-Sulpice-Pélissier.

En 2013, du fait du vieillissement des infrastructures, la ligne à 225 KV qui reliait à l'époque Pélissier à Verfeil a été raccordée à Brens avec un réaménagement du poste. Pour compenser la suppression de cette ligne électrique et de celle reliant Brens à Gaillac, deux liaisons souterraines à 63 KV ont été créées.

## Description du tracé:

* La ligne débutait au poste de Gaillac où elle partait en direction du nord-est puis elle redescendait vers le sud-est à l'est de la ville ou elle passait sur le Tarn.
* Au niveau de Brens, elle se redirigeait vers le nord-est et repassait sur le Tarn avant de se rediriger vers Albi au sud de la N88.
* Au nord de Marssac sur Tarn, elle se mettait sur une petite portion en double circuit avec la ligne reliant Lisle sur Tarn à Pélissier.
* Plus loin, elle passait dans la ville de Castelnau de Lévis puis après quelques kilomètres, elle passait sur la D600 avant d'arriver au poste de Pélissier.
