Présentation

• La route nationale 621, ou RN621, est une ancienne route nationale française qui reliait Toulouse (RN113) à Mazamet (RN112), via Puylaurens.

Historique

• À sa création, en 1933, elle est définie comme la route de Toulouse à Mazamet, par Soual-l'Estap.
• Dans la Haute-Garonne, elle est issue de la route départementale n° 1, ou RD1 (31). Dans le Tarn, elle est issue du chemin vicinal de grande communication n° 82, ou Gc82 (81), pour la section comprise entre la limite de la Haute-Garonne et Soual et du chemin vicinal de grande communication n° 88, ou Gc88 (81), pour la section comprise entre Soual et Mazamet.
• La déviation Nord de Mazamet est mise en service en 1956. Elle est désormais en milieu tellement urbanisé qu'une nouvelle déviation est en projet plus au Nord.
• Suite à la réforme de 1972, le tronçon Toulouse - Soual a été renommé en RN126, partiellement déclassée en 2006 entre Toulouse et Scopon, et le tronçon Soual - Mazamet a été déclassé en D621. Avec la mise en service de la Rocade Sud de Castres dans les années 2000, le tronçon Labruguière - Mazamet a été réintégré à la nouvelle RN112.
• Depuis le 1^er janvier 2017 son exploitation est assurée par Toulouse Métropole entre Toulouse et Drémil-Lafage. En conséquence, elle devenue une route métropolitaine, les cartouches ayant été changés sur le terrain en 2021, soit M126 et M826.

Futur

• Aménagement de l'axe Toulouse - Castres (route express à 2x2 voies).
• Aménagement Castres - Mazamet (route express à 2x2 voies).
