Final answer:
Wide boulevards in cities of Less Developed Countries are generally developed during stages of urbanization influenced by historical planning, like the Law of the Indies, or modern structured development aimed at improving city infrastructure.
Step-by-step explanation:
Wide boulevards in cities of Less Developed Countries (LDCs) are often associated with stages of urbanization influenced by colonial histories or specific urban planning strategies. For instance, during Spanish colonial rule, urban planning followed the Law of the Indies, leading significant Latin American cities to feature wide boulevards stretching from central plazas, filtering into areas where the elite resided.
In other cases, as cities in LDCs expand rapidly due to urban migration, there is a shift from chaotic growth to more structured development, which may include the planning of such grand boulevards as a means to improve infrastructure and accommodate the growing population and their need for amenities like healthcare and education.
It's during the transformation and substantial growth periods that you might find the development or expansion of wide boulevards in LDC cities. These boulevards serve various purposes, ranging from ceremonial to practical, such as providing efficient transportation routes and reflecting aspects of modernity and development within the urban landscape.
