Incessant rain that triggered landslides in Himachal Pradesh killed 71 people in the last three days with the state now facing a monetary loss of ₹75,000 crore in this year's monsoon.
Redeveloping the infrastructure that got washed away in the rain will take at least a year, chief minister Sukhvinder Singh Sukhu said.
All educational institutes in Shima will remain closed on Thursday as roads are blocked owing to frequent landslides.
The state government has urged the Centre to declare national calamity in Himachal Pradesh.
Himachal already received more rainfall than the season's average until August.
In the 54 days of monsoon this year, the state received 742mm of rainfall against the season's average of 730mm.
The rainfall recorded in the state this July broke all records for the month in the last 50 years leading to the most devastating natural calamity in the last 50 years.
