Bolshaya Koltsevaya line
Moscow Metro line
The Bolshaya Koltsevaya line (Russian: Большая кольцевая линия) (English: Big Circle Line) (Line 11; Teal Line) is a rapid transit line of the Moscow Metro system in Moscow, Russia. It is the third circle line on the system, running outside of the existing circle Koltsevaya line and interlocking with the Moscow Central Circle.
The first section of the line opened on 26 February 2018, with the remaining stations opening on 1 March 2023. The line includes 29 stations, including three from the former Kakhovskaya line, and is 57.5 km (35.7 mi) long, which makes it the longest metro circle line in the world, surpassing Line 10 of Beijing Subway by 514 m (1,686 ft). In November 2017 the city estimated the total cost of the project at 501 billion rubles, up from earlier estimates of 378.9 billion rubles.
Formerly known as the Third Interchange Contour, the city adopted "Bolshaya koltsevaya liniya" as the official name of the line after a vote via the "Active Citizen" web portal.
Name
The working name of the project since inception was the Third Interchange Contour; however, prior to the opening of the line, the city authorities consulted residents to help decide on the name. In an initial survey on the Active Citizen survey website in October 2017, only 34% of the city’s residents voted to keep the working name.
Although retaining the working name was the most popular option, members of the city’s council on transportation infrastructure suggested another vote. Two reasons cited by transport expert Kirill Yankov were that all of the lines’ names to this point were in the feminine grammatical gender and that all the other line names were generally understood from a point of view of geography.
This brief starts where responsible research should: with the source description of “Bolshaya Koltsevaya line” as moscow Metro line. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as moscow Metro line. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q617574. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2018, 2023 and 2017.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
