High fibre solution to wobbly bridge


Observing with interest the problems with the new Thames footbridge, it seems to me that instead of trying to dampen the vibration of tension cables it may prove more prudent to replace the existing structure with a nice slender carbon fibre beam, sitting on the existing piers.

Based on experience of building large carbon fibre structures for highly demanding marine conditions, I suspect the cost of a composite beam to be less than the that of stopping tension cables vibrating, if indeed that can be done.

Barry Noble,
