“Sky bridge”, “skywalks” or “elevated walkway” bring up images of a narrow, glass walkway connecting two towers – usually commercial – the only purpose of which, is to let people go from one meeting to the next without having to travel up and down or through fresh air.

In the 1960s, sky bridges were seen as radical urban interventions which brought in the third dimension into city circulation. Victor Gruen, an American architect, championed the movement of the sky bridge. And cities all over the world, followed suit, with varying degrees of success. While a few have achieved the fluid connection between buildings, the rest turn bridge walking into thrill seeking.

Today, sky bridges are seen in airports, malls, transit hubs, hospitals etc, acting as a thoroughfare, standing beside greenery. Some architects, however, design sky bridges sky high. They straddle the top floors of some of the tallest structures in the world. Petronas Tower, the Linked Hybrid, InTempo are few examples that fit the bill.
Architects have begun to show renewed interest, in the past decade, in sky bridge as an architectural element. Certain structures use the elevated walkway primarily as a means of circulation. Others design the sky bridge to remain a separate entity not included as a part of the circulation network.

Here are a few interesting works of architecture with stunning skywalks.
