Rolling Bridge
Rolling Bridge
1. Rolling bridge

This 39-foot timber and steel bridge was built in 2004 to act as a walkway over a small section of London's Grand Union Canal. An innovative hydraulic system in the bridge's handrail allows it to retract and curl into an octagon, which it does every Friday at noon.
2. The Gateshead Millennium Bridge

The Gateshead Millennium Bridge is sometimes referred to as the 'Blinking Eye Bridge' or the 'Winking Eye Bridge' due to its shape and its tilting method. It’s a pedestrian and cyclist tilt bridge spanning the River Tyne in England.
3. Moses Bridge

Designed by architecture group RO & AD, The Moses Bridge is constructed out of Accoya wood, a hi-tech wood that is supposedly harder and more durable than some of the best tropical woods. It is treated with a nontoxic anti-fungal coating to maintain its split-the-water functionality.
4. Henderson Waves Bridge

This nearly 900-foot pedestrian bridge is the highest of its kind in Singapore, connecting two parks. The bridge has a wave-form made up of seven undulating curved steel ribs that alternately rise over and under its deck. The curved ribs form alcoves that function as shelters with seats within.
5. Pont Gustave-Flaubert

Instead of separating in the middle like a drawbridge, the Pont Gustave-Flaubert's deck is lifted straight up by a butterfly-shaped pulley system so tall ships can pass through.
6. Langkawi Sky Bridge

This curved pedestrian bridge is 2000 feet above sea level at the top of Mount Mat Cincang in Malaysia. Tourists who want to walk across the 400-foot long structure must ride up to it in a cable car.
7. Pythonburg

The sinuous Pythonbrug is one of the most modern bridges in Amsterdam, a city famous for its traditional canal bridges. Unlike Singapore's Henderson Waves, which relies on an outer shell to create the wave illusion, the Pythonbrug walkway actually dips and rises. While the bridge is certainly an eye-catcher, MacDonald points out that its steep incline wouldn't pass muster under the Americans With Disabilities Act, which sets a 5 percent limit on the grade of such structures.
8. Oresund Bridge

The Oresund Bridge is an incredibly complex structure that begins as a cable-stayed bridge in Sweden and ends as a tunnel in Denmark. A small artificial island was built around the tunnel's entrance to keep water from creeping in. Not only is the bridge equipped to handle four lanes of traffic.
9. Slauerhoffbrug

The Slauerhoffbrug is a tail bridge that can quickly be raised to allow ships to pass. It was completed in 2000 and spans a small section of the Harlinger Vaart River.  Instead of rotating open, the Slauerhoffbrug is lifted up by a dual hydraulic systems that is built into its pylon. The Slauerhoffbrug is L-shaped, with its foundation sitting adjacent to the road.
10. Sundial bridge

As its name implies, the bridge's 217-foot-tall support tower acts as a giant sundial. The deck of this pedestrian bridge is made from nonskid glass panels to give walkers a greater sense of the river.
