D26 track extension from the Virage de la Hovette (Annie Bousquet corner) to a new purpose built intersection with the La Garenne straight (Muizon corner) about west of the previous Gueux / La Garenne junction, resulting in a new preliminary circuit length of . The last major modifications were before the 1954 season, re-profiling the new Muizon corner from the previous year and the Thillois corner to a larger and faster radius, which established again a shorter and final circuit length of . This public road circuit had previously been made up entirely of straights with a few slight and very fast kinks and slow corners; with the addition of these 3 fast sweepers and the extension of the main straight, this circuit, which was already very fast- was now even faster than it had been before, by about 4-5 mph per lap. The last year for Formula One at Reims came in 1966, final sports car competitions were held in 1969 and Motorcycle racing continued for another 3 years. In 1972, Reims-Gueux closed permanently due to financial difficulties. There was to be a historic race held in 1997 but it was cancelled for technical reasons several months before it was due to take place and by 2002, the bulldozers arrived to demolish some portions of the track. A few sections of the old circuit are still visible today around the pit lane, at the D26 / D27 round-about and a part of the D26 extension at the Hovette corner to what once was the 1953 Muizon hair-pin (visible on current sat. images). Today, the old RN31 straight between Muizon and Thillois is a wider dual carriageway, although it does follow the same line as the original two-lane road of the former circuit. It is still possible to drive a lap around the (more or less) original 1926 version (through the center of Gueux) and the 1952 variant of the circuit, except for the old Garenne -junction which was demolished as part of the RN31 modernization. It is no longer possible to complete a lap of the circuit used from 1953 onwards as the tarmac between Bretelle Nord and Muizon has been removed. Les Amis du Circuit de Gueux (a non-profit organization) is working to preserve the old pit building, grandstands and other remaining structures of the circuit and actively support historic meetings which use the 1952 Circuit d'Essais.
