Great article on a project I remember well. I think it would be interesting to compare the coating performance of the HRCSA system with the three-coat system used on the Dawson Bridge rehabilitation (1915 bridge downstream of the High Level Bridge) carried out approximately 7 years ago now.

Interesting - I was riding across the pedestrian path of the High Level bridge two weeks ago and witnessed many areas of complete coating disbondment / missing coating. I'd be glad to share pictures of this.
