I want to know the answer to the following question:
When did the era of planning start in Himachal Pradesh?
All the background I'm provided with is that "More than 50% of this expenditure was incurred on road construction since it was felt that without proper transport facilities, the process of planning and development could not be carried to the people, who mostly lived an isolated existence in far away areas.". Is that enough to answer the question?
Answer: no
