National road infrastructure plays a significant role in promoting urban sprawl by improving accessibility to peripheral and rural areas. When new roads are built or existing ones are expanded, land along these corridors becomes more attractive for residential, commercial, and industrial development. This often leads to the spread of urban areas beyond traditional city boundaries, especially in regions with weak land-use regulations. Over time, this can result in fragmented development, loss of agricultural land, increased car dependency, and challenges in providing public services and infrastructure.
