In Soviet times the M04 was part of the M21. The highway stretched through four oblasts and ended at the Izvaryne-Donetsk border checkpoint which is part of Krasnodon city (Luhansk Oblast). The section from Znamianka to Debaltseve was part of European route E50, and the section from Debaltseve to the Russian border was part of European route E40. On 28 April 2021, the M04 was decommissioned and merged with the M12 to form the new M30.
