The Moscow Ring Road (MKAD) was opened in 1961. It had four lanes running along the city borders. The MKAD marked the administrative boundaries of the city until the 1980s, when outlying suburbs beyond the ring road were incorporated. In 1980, Moscow hosted the Summer Olympic Games, which were boycotted by the US and other Western countries due to the Soviet Union's invasion of Afghanistan in 1979. In 1991 Moscow was the scene of a coup attempt by conservative communists opposed to the liberal reforms of Mikhail Gorbachev.
