History
Along with the Moscow Big Ring Road, the Moscow Small Ring Road was built in the 1950s and 1960s to meet the military transport needs of Moscow's air defenses. There is a widespread opinion that concrete blocks were built precisely from concrete slabs, which were supposedly laid on top of each other in several layers so that the canvas could withstand mobile missile systems. Concrete was poured along technological grips{{Clarification needed|date=August 2022}}, each of which was 200–300 meters long. The width of the roadway was from 4 to 5 meters; the thickness of the concrete was no more than 25 centimeters, and in some places only 15 centimeters, but capable of withstanding the weight of multi-ton rocket tractors.
Until 1990, the Moscow Small Ring Road was not marked on maps and in road atlases.{{cite web|url=http://www.avp.travel.ru/trass_enc/A-107-108_trass_enc.htm|title=А-107 (ММК) и А-108 (БМК). Малое и Большое подмосковные кольца.|work=avp.travel.ru}} Information about convenient roads eventually spread among the local population, and both rings became public roads, first de facto, and in the late 1980s de jure. Gradually, the concrete slabs were covered with asphalt, but in the popular consciousness, the rings remained “concrete”.{{cite web|url=http://www.ogoniok.com/4955/16/|title=Рассекреченная трасса|archiveurl=https://web.archive.org/web/20120112103055/http://www.ogoniok.com/4955/16/|archivedate=12 January 2012|work=Ogoniok}} In 2016, the construction of the Central Ring Road toll road began, especially through Malaya Betonka.{{cite web|url=https://odintsovo.info/news/?id=70219|title=Утверждён список платных участков ЦКАД|work=odintsovo.info}}
