It cost the exchequer Rs 2.92 crore.

Sonowal dedicating the flag to the people told the gathering that Gandhiji's philosophy of non-violence, cleanliness, untouchability is still relevant not only in India but outside the country too.

"Even the greats like Nelson Mandela, Martin Luther King followed Gandhiji's philosophy to serve humanity. Gandhiji was a great humanist and nationalist. Installing the tallest National Flag in the state was motivated by Gandhiji's principle of nationalism," he said.

The National Flag installation project was conceived by Sonowal and he had asked the department of industries and commerce to implement it. Guwahati Smart City Ltd was entrusted with the task of preparing the project document and supervising the work, officials said.

"The total project cost is Rs 2.92 crore, which includes operations and maintenance for a period of one year," the release said.
