A metaphor for a never-ending-task is like painting the Forth Bridge and in many ways it was true as the bridge has been continuously painted over and over during the first 112 years of its 120 year lifetime.
Since 2002, there has been an ongoing programme of blasting the paint and rust back to the base metal and repainting with an application of zinc based primer to prevent corrosion (35 microns); a glass flake epoxy intermediate coat providing a barrier (400 microns); and, a polyurethane gloss top coat to give an attractive “Forth Bridge Red” finish (35 microns) on all of its estimated 400,000m² surface.
The new paint is expected to last between 25 and 40 years although some of the more exposed sections will need attention more frequently.
Completion dates have slipped continuously since the start of the project with the latest prediction claiming that it may be finished by Christmas 2010 (I’m not going to hold my breath).
The bridge has looked pretty ugly at times as parts of the bridge are permanently covered in huge sheets of plastic.
This shot from the South Queensferry side, shows the North section (there are three identical sections in total) which appears to be complete and thus free of plastic.
The day all the plastic comes off it will be difficult to get close for the thousands of photographers who will be lining both river banks as well as the walkway on the Forth Road Bridge.
