The Prime Minister of Nepal, KP Sharma Oli, made a pledge on December 5, 2015 that the road will be "constructed in two years," siting that it will become the shortest link between China and India, as reported by the Himalayan Times. Completion of the road includes the construction of two major bridge projects (one of which is underway near the sit of the 900 megawatt Arun III hydropower project) and the completion of track through dozens of miles of steep jungle terrain. It is ambitious goal, no doubt, in a country where setbacks due to corruption and slow government bureaucracy are commonplace. Indeed, the government is now becoming infamous for empty promises, but this does confirm that the project is of significant national interest and it's completion is a priority for the government. Whether it can be completed in 2 years or not, well... only time will tell.
