What objectives did the British intend to achieve through policies of infrastructural development in India?

The true motive of British behind the infrastructural development was only to serve their colonial interest. There was infrastructural developments in the fields of transport and communication.
(ii) The roads served the purpose of facilitating
transportation of raw materials from different parts of the country to ports and ports were developed for easy and fast exports to and imports from Britain.
(iii) Railways were introduced and developed for
the transportation of finished goods of British industries to the interiors of India. Railways assisted British industries to widen the market for their finished products.
(iv) Posts and telegraphs were developed to
enhance the efficiency and effectiveness of the British administration.
Hence, the aim of infrastructural development was not the growth and development of the Indian economy but to serve their own interest.
