R-21 regional road (Montenegrin : Regionalni put R-21) is a Montenegrin roadway. ^[1]

This road serves as a shortest connection between Šavnik and Kolašin.

History

In 1975, a tunnel under the Semolj was started. It would have been 1750 m long, and 420 m were excavated before the work was stopped the same year. ^[2]

In January 2016, the Ministry of Transport and Maritime Affairs published bylaw on categorisation of state roads. ^[1] With new categorisation, part of R-18 regional road between Tušina and Mioska was renamed as R-21 regional road.
