The road from Trashigang to Samdrup Jongkhar was completed in the early 1960s and enables the eastern half of the country to access the benefit from the trade in the south as well as providing a border crossing to India. It is possible to exit Bhutan and drive from Samdrup Jongkhar to Phuentsholing via the Indian territories of Assam and West Bengal.The journey from Trashigang passes through Kanglung, a small hamlet where Bhutan's only college, Sherubtse or Peak of Knowledge is located. Further south along the road is Khaling where one can visit a weaving center and a school for the blind. Pemagatshel is an independent district with its own dzong. The road descends fairly abruptly through thick jungle before arriving at Samdrup Jongkhar. This town is small and bustling and acts as a commercial hub and entry and exit point in the southeast. Samdrup Jongkhar is only 110 kms away from Gauhati the capital of Assam state. Phuentsholing is the southwest border town and can be used as an entry and exit point for Bhutan which is 160 kms from Bagdogra airport in West-Bengal.
