The Wobbly Bridge
A modern engineering masterpiece or a 'Bridge too Far?'. What
was a bold idea to guide visitors from St. Pauls Cathedral, across the
Thames, to Bankside (now Tate Modern) was disappointingly executed. The
new bridge nicknamed the 'wobbly bridge', because of its tendency to
sway when people walked over it, closed on 12th June 2000, just two days
after it opened!

Flashback to June 2000, open day for the bridge...
The 320 metre London
Millennium Bridge was designed by Lord Foster. Its
construction of steel and aluminium signifies a 'Blade of
Light' linking the two shores.

walking on escalator steps.

A Bridge too Far?
Following an international competition in December
1996, a team of designers and engineers was appointed to construct a new
bridge across the Thames.
Client:
London Borough of Southwark
London
Millennium Bridge Trust
Design Team:
Architects and Designers -
Foster and
Partners
Sculptor - Sir Anthony Caro-Barford Sculptures Ltd
Quantity
Surveyors - Davis Langdon & Everest
Engineers:
Arup
Arup's other projects include the
BT Tower lifts.
The bridge was opened on 10th June 2000, but due to excessive swaying,
caused by the footfalls of large numbers of pedestrians walking across,
it was closed on 12th June. As a result of this, Arup set to work with
engineers from the Universities of Southampton, Sheffield and London and
architects of the Millennium Bridge, Foster and Partners, to find a
solution.
By late 2000, Arup had installed a prototype damping system to
limit movement of the bridge.
This comprised of:
- four chevrons
- two
viscous dampers
- one tuned mass damper.
|
This was tested and proved to eliminate the excessive lateral movement,
thus making the bridge comfortable for all to use. The full solution was
expected to take six months to install and the bridge was due to open
for the Summer of 2001. In practice, the bridge did not re-open until
the 22nd February 2002.
