Bolshaya Koltsevaya line

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.[6]

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 line’s 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.[7] The city held another vote on its website to allow citizens to choose between the existing name or the Bolshaya Koltsevaya line (Large Circle Line). Of the alternate names suggested by voters in the first vote, Bolshaya Koltsevaya was the most popular, with 9,000 votes.

In the second vote, Bolshaya Koltsevaya was selected with 53.3% of the votes versus 36.5% for the Third Interchange Contour.[5]

Initial construction timetable for the Bolshaya Koltsevaya line

The original plans called for a 58-kilometer line with 27 new stations.[8]

The entire project was supposed to be completed by 2020–2021.[1][9][10][11][12] By 2018, the completion date had been postponed until the end of 2022.[13]
