Design unveiled for Nepean River Green Bridge
1 day ago
"In order to make the best use of the limited maintenance resources and not compromise the effectiveness of the coating, the council’s bridge engineer would need to be completely convinced any treatment would not be detrimental and would oppose any proposed treatment involving the application of a corrosive de-icing material."Well, duh. How did they think they would maintain the bridge when it was built? What is the paintwork on the bridge for if not to protect it against corrosion? Attempting to defer the inevitable repainting of a 9-year old structure may be understandable on pure cost grounds, but failing to keep the structure clear of ice seems a crazy consequence to accept. In any event, there are surely deicing products available which are less corrosive than the traditional road salts.
The organisers are very keen to promote innovative use of materials, so it will be interesting to see what emerges in January when the winning design is to be announced.
