Urban Voids are spaces that rupture the urban fabric of a city. These are spaces that are often neglected or forgotten spaces in the eyes of people. They are often the result of designing out of context with the surroundings. They are the result of treating planning sites in isolation regardless of urban fabric and poor design.

The uniqueness of flyovers lies in its character of an overhead shelter with its generous underneath space that is longitudinal and barrier free. It is sheltered from the rain and from the heat of the sun. The term ‘flyover’ is used in the United Kingdom and most Commonwealth countries and is defined as a bridge that carries a road or railway over another road (“Flyover), which is a bridge, road, railway, or similar structure that crosses over another road or railway. An overpass and underpass together form a ‘grade separation’. ‘Stack interchanges’ are made up of many overpasses. A pedestrian overpass allows pedestrians to safely cross over busy roads.
