Bridge of Aspiration, Royal Opera House, London
Decorative, functional and highly symbolic, the Bridge of Aspiration by WIlkinson Eyre Architects links the Royal Ballet School to the Royal Opera House. It’s literally the access point for ballerinas to enter the Opera House for a performance. It’s made of ‘a concertina of 23 square portals with glazed intervals’ rotating in sequence to skew in alignment, performing an appropriately graceful quarter-turn along the length of the bridge.
Petronas Twin Towers Skybridge, Malaysia
Twin skyscrapers in Kuala Lumpur, Malaysia which were the tallest buildings in the world from 1998 to 2004 are linked by a double-decker skybridge on the 41st and 42nd floors, the highest 2-story bridge in the world.

It offers visitors views of the city, and also functions as a safety devices, so tenants can evacuate from one tower into the other.
