The Third Ring Road
, or The Third Ring
, (Тре́тье тра́нспортное кольцо́, Тре́тье кольцо́) is Moscow
's newest beltway
, located between the Garden Ring
in the city centre and Moscow Ring Road
, which until the 1980s defined the Moscow city limits.
The Third Ring is 35 km in length, i. e. about 10 km in diameter. As it is one of Moscow's main roads there is a lot of traffic on it and frequent congestions. There is a planned Fourth Ring between the Moscow Ring Road and the Third Ring.
The Third Ring can be utilized to go to Sheremetyevo Airport from the other side of the city from such areas as Sparrow Hills. The road is used by many Moscovites who live in the suburbs of Moscow.
The Third Ring was completed in 2004 with the Lefortovo tunnel, the third longest urban tunnel in Europe.
