• Suite à la suppression des routes stratégiques, en 1862, la RS20 devient la D3 dans l'Ille-et-Vilaine et la D12 dans la Mayenne.
• Dans les années 1930, son tracé est intégralement récupéré par la nouvelle RN798, déclassée en 1973 en D30 et D798.

• Intégralité de l'itinéraire : 1835 (parachèvement en 1836).
