Layout — RGC (High Traffic Road) Backup Perimeter in Loir-et-Cher

The Dupont Amendment of 2 February 1995 (Art. L111-1-4 of the Urban Planning Code) is a safeguard measure designed to ensure the quality of non-urbanised areas located on the edge of a major roadway. Attributes are the designation of the section concerned, the date of the classification decree and the width (75 m or 100 m on either side of the axis) where new constructions outside urbanised areas are prohibited. High-traffic roads, regardless of whether they belong to the State, are roads which ensure the continuity of the main routes and, in particular, the diversion of traffic, the movement of exceptional transport, convoys and military transport and the economic services of the territory, and, as such, justify special rules on traffic police. The list of RGC routes (defined in Article L. 110-3 of the Highway Code) is established by a decree in the OJ.
