Présentation

• La Route impériale 24 était une route impériale française de 2^e classe qui reliait Paris à Barèges via Limoges, Agen et Tarbes. Cette route devait à l'origine atteindre l'Espagne via Gavarnie mais, dans les faits, elle ne fut jamais achevée.
• Après la chute de l'Empire, la Route impériale 24 est devenue la Route nationale 21. Cette route est une des rares a être presque entièrement conservée de nos jours, en vue de son aménagement en voie express. Seule la section Argelès-Gazost - Gavarnie a été déclassée en 1973 suivie par la section Lourdes - Argelès-Gazost en 2006 et par la section Astaffort - Rabastens-de-Bigorre en 2024.
