Sky bridges are elevated walkways that connect two or more buildings, often found in urban areas. They provide a safe and convenient way for pedestrians to move between structures without having to go to the ground level. These bridges can enhance accessibility and reduce traffic congestion, especially in densely populated cities. Typically made of glass or steel, sky bridges can offer stunning views of the surrounding landscape. They are often designed to be aesthetically pleasing, contributing to the overall architecture of the buildings they connect. Some famous examples include the Petronas Towers in Kuala Lumpur and the Marina Bay Sands in Singapore.
