R-1 regional road () is a Montenegrin roadway.
Between Čekanje and Njeguši there used to be 7 hairpin turns, but after the tunnel was excavated in 2018, only 3 are still on this route. After Krstac, going down the western mountainside of Lovćen towards Kotor, there are an additional 25 hairpin turns.
History The section of the R-1 regional road between Cetinje and Krstac (Njeguši) is the oldest vehicular road in Montenegro. It was built after Montenegro was recognised as an independent state at Congress of Berlin in 1878. Construction begin in 1879, and was finished in 1881
The reconstruction of the road between Bajice (village at the outskirts of Cetinje) and Krstac took place in 2017 and 2018. The road was widened from 4 meters to 6.6 meters and the radius of curves was increased. Between Čekanje and Njeguši a 490 meters tunnel was excavated, bypassing hairpin turns. All of this shortened the road for 3.5 km and at the same time increased the speed.
