A new capital was seen as a more economically viable alternative than attempting to reorganise and restructure Dar es Salaam and was idealised as a way of diverting development away from continued concentration in a single coastal city that was seen as anathema to the government's goal of socialist unity and development. Objectives for the new capital included: that the city become a symbol of Tanzania's social and cultural values and aspirations; that the capital city function be supplemented by industrial-commercial development; and that the mistakes and features of colonial planning and modern big cities, such as excessive population densities, pollution and traffic congestion, be avoided.
