The prime minister of India, Manmohan Singh, has led thousands of people on the final day of the re-enactment of a historic freedom march in 1930.
The 26-day walk took place from the western city of Ahmedabad to Dandi on the Arabian Sea coast.
It traced the route of Mahatma Gandhi's march to collect salt in defiance of a tax imposed by the British rulers making it illegal to harvest salt.
Mr Singh urged the 200,000-strong crowd to follow Gandhi's message of equality.
He also said the government would provide funds for the development of the heritage route and build memorials along it.
The leader of the Congress Party, Sonia Gandhi, said no country could progress unless it followed the Gandhian ideals of truth, brotherhood and peace.
Correspondents say the march has coincided with a 4% VAT tax on processed salt by most state governments - the first tax on salt since Indian independence.
