Not wanting to put a damper on things

Letters

Now the full extent of the engineer's remedial measures to dampen the vibrations of the Millennium Bridge are known, it is time a structural solution without dampers should be fully investigated.

A bridge of this length should have had a full length lateral bracing system designed to suit the structure. So called 'chevron bracing' is not bracing at all. It is a mechanical device.

A structural solution would be to add the diagonal members required in the deck to make an effective lateral bracing system.

Also tensioned wire rope bracing should be added between the cables and the deck. These would be stainless steel, of small diameter (up to 25mm) and use straining screws, all available at any steel stockist or ships' chandler, and would not cost even £1M.

The opportunity should be taken now to save this unique bridge as an engineering structure rather than perpetuate it as an engineering folly.
