The tilting Gateshead Millennium Bridge spanning the River Tyne between Gateshead on the south bank and Newcastle upon Tyne, England, on the north is a pedestrian bridge with two large hydraulic rams at each side that tilt the structure back allowing small watercraft to pass under.
Why does the Millennium Bridge tilt?
The word redounded Gateshead Millennium Bridge is built in a semi circle. This way when the mechanics are fired up and the bridge tilts to the left it will create an opening passage for any ships passing through underneath.
How does the Gateshead Millennium Bridge work?
The bridge form, a pair of steel arches spanning 100m between concrete islands, rotates 40 degrees to permit vessels to pass beneath. The bridge deck provides both a footway and separate cycleway, taken in a wide curve across the river.
What is unique about the Gateshead Millennium Bridge?
Winner of the 2002 RIBA Stirling Prize, this unique crossing for pedestrians and cyclists was the world’s first tilting bridge. It has become a new landmark for Gateshead and the Tyne, a river famous for its historic bridges.
Does the Millenium bridge move?
The bridge takes around four minutes to rotate through the full 40° from closed to open, moving as fast as 18 mm (0.71 inches) per second.
How does a tilt bridge work?
As the arch tilts lower, the pathway rises, each counterbalancing the other so that a minimum of energy is needed. The resultant appearance in motion leads to it sometimes being called the “eyelid bridge”, since its shape is akin to the blinking of an eye if seen from along the river.
How did they stop the Millennium Bridge from wobbling?
They concluded that making the bridge stiffer, to move its resonant frequency out of the excitation range, was not feasible as it would greatly change its appearance. Instead, the resonance was controlled by retrofitting 37 viscous fluid dampers to dissipate energy.
What is the highest point in Gateshead?
Currock Hill
Currock Hill is a hill in Tyne and Wear, England, which at 259 m (850 ft) is the highest point in the county, and in the metropolitan borough of Gateshead.

Is it normal for bridges to move?
Bridges can move for two reasons: engineers build them to move, or sometimes natural forces (or poor construction) cause movement. The harmful types of shifting that can affect bridges are resonant frequencies, aeroelastic flutter, and thermal expansion and contraction.
How long does it take to walk across Millennium Bridge?
about 5 minutes
It only takes about 5 minutes to cross, taking in the sights as you go, but there are great attractions at either end including St. Paul’s, Tate Modern, the Globe and the Golden Hind.
How do dental bridges stay in place?
To place a fixed bridge, your dentist uses an existing natural tooth or teeth to help hold your bridge in place. Fixed bridges are cemented in place and only a dentist can remove them. This makes them feel stable and very similar to your natural teeth.
Why some bridge are not straight?
Arch bridges are bridges that have a curved shape. The curve helps to dissipate the force of the load (the weight of the people and things on the bridge) outwards instead of downwards like on a linear bridge. This means that the bridge can handle more weight without breaking.
What keeps a bridge from falling down?
Abutment: Abutments are the elements at the ends of a bridge that support it. They absorb many of the forces placed on the bridge and act as retaining walls that prevent the earth under the approach to the bridge from moving.
