The road condition in between Paro, Thimphu and Punakha/Wangdue is black topped and is in good condition.
The road from Wangdue to Gangtey Valley, the half way road is already black topped and half way is under the widening project and not very fun to drive in.
Also, the section from Gangtey to Bumthang via Trongsa is also under the widening project and hoping to complete soon.
