The road between Paro, Thimphu and Punakha/ Wangdue is black paved and is very comfortable for drive.
The road stretching from Wangdue to Gangtey Valley is undergoing the widening project however the half of the road is already paved and is in good condition while half is uncomfortable for drive. The road section from Gangtey to Bumthang via Trongsa is also undergoing a widening project so travelers might have some difficulties during the drive.
