The development plan of KKHT Highway has been initiated in the context of much talked about and most desired short cut route out of the valley. This highway will connect entire western followed by southern and eastern parts of Nepal through Hetauda and will significantly boost overall economic growth of the corridor, region and the whole country.

The Hetauda-Narayanghat-Mugling-Kathmandu passage is one of the highest trafficked road corridors in Nepal. Most of the goods from India or third countries are brought to Kathmandu via this route from Birgunj and other places. The road length from Hetauda to Kathmandu is approximately 227 km with travel time of approx. 6-8 hrs. The alternative route – the Tribhuvan Highway, though only 133 km in length still requires travel time of approx. 7-8 hrs. Whereas the purposed KKHT Highway will connect Kathmandu with Hetauda via Kulekhani in an hour.
