The Third Ring Road also serves as the main highway access for the Moscow International Business Center (MIBC), a modern high-rise office district located along the western portion of the Third Ring, where it crosses the Moscow River.

The northern sections can be identified as this type of highway due to its access to adjacent property and many intersections with streets.

The Third Ring Road then underpasses the 12-lane Leningradsky Avenue with a variant diamond interchange that includes a few overpasses.

These sections can be identified as this type of highway due to its lack of access to adjacent property and no intersections with streets; however, there are some exceptions.

Later, the Third Ring Road forms a hybrid interchange with Yuzhnoportovaya Street and the beltway splits to make the MCC line as a median strip.

The MCC Line later underpasses the southern lanes of Third Ring Road, thus ending its purpose as a median strip.

Now the Third Ring Road was over one-fourths completed, with the western, eastern, and southern branches needed to be built.

On May 10, 1999, the overpass over the Luzhnetskaya Thoroughfare from Komsomolsk Avenue to Berezhkovsky Bridge was built and opened.

The area east of the beltway north of Moskva River after crossing the Dorogomilovsky Bridge would become the MIBC.

A tunnel interchange on Nizhnyaya Maslovka Street which goes under the beltway was built and opened on August 28, 2001 in the northern parts of the highway in the Savyolosky District.

It was constructed along with a section to Volgograd Avenue of southeastern central Moscow, with a reconstructed Avtozavodskii Bridge, on December 12.

In the same year, the section between Shmitovsky Avenue and the Zvenigorod Highway was completed although the date is not clarified.

The section between Ostapovsky Thoroughfare and Nizhny Novgorod Street on the eastern part of the beltway were built and opened on the same time as well.

The area between Spartakovskaya Street and the Krasnokazarmennaya embankment by the Yauza River were finished in the Basmanny District on October 1, 2003.
