The Third Interchange Contour (Russian: Третий пересадочный контур, Trety peresadochny kontur, IPA: [ˈtrʲetʲɪj pʲɪrʲɪˈsadətɕnɨj ˈkontʊr]) (Line 11) is a rapid transit line of Moscow Metro under construction. It is planned to be a second circle line running outside of the existing Koltsevaya (Ring) Line, with a branch to Moscow-City.

Third Interchange Contour Map

The existing, short, three-station Kakhovskaya Line will be incorporated into the Third Interchange Contour. Besides this, the first new stations were expected to be opened by December 2015. However, as of November 2015, 2018 is being reported as a more likely for the completion of the whole project. The five stations from Petrovsky Park to Delovoy Tsentr are scheduled to open first, in 2016.

Continuing the ring

In 2016, the Northeastern section is scheduled to be completed. This section includes the part of the line from Nizhnyaya Maslovka to Aviamotornaya. The Third Interchange Contour will run from Aviamotornaya to Nizhegorodskaya Ulitsa along the same routing as the Kozhukhovskaya Line, which is also scheduled to open in 2016.

By 2017, the Eastern section from Nizhegorodskaya Ulitsa to Kashirskaya is scheduled to be complete. This will connect the Third Interchange Contour to the present-day Kakhovskaya Line, the first part of the outer ring line to open in 1969.

Completing the ring

Current plans call for the rest of the Third Interchange Contour to be opened in November 2018. The remainder of the ring is split into two projects:

• Southwestern Section - from Kuntsevskaya to Prospekt Vernadskogo
• Southern Section - from Prospekt Vernadskogo to Kakhovskaya
