The damage caused by the earthquake has earlier created uncertainty about this year's Kailash pilgrimage.
However, China said preparations for the new route were made keeping up with the schedule.
China has agreed to open the second route, which is completely accessible by road during last year's visit of Chinese President Xi Jinping to India. Prime Minister Narendra Modi had made a request to Xi on the issue.
About 250 people were expected to take part in batches to go to pilgrimage in batches.
India wanted the route as it facilitates journey by buses directly from the border point to Kailash without the ordeal of trekking and travel on horse backs.
With this, the pilgrims will have two routes, one through Lipulekh Pass in Uttarakhand and another through Nathu La.
