Forth Bridge painting to finally end in December

Painting work on the Forth Bridge that began in 2002 will finally come to an end on 9 December this year, ahead of schedule, Balfour Beatty Regional Civil Engineering has said.

Network Rail and main contractor Balfour Beatty Regional Civil Engineering will preside over what they are calling “the end of a modern myth” when the refurbishment work is completed. Painting of the bridge will likely not begin again for over 20 years.

“The current restoration work has been ongoing since 2002 but, owing to years of underinvestment during the 1970s and 1980s, the scale of the job was initially unclear,” said Network Rail Scotland route managing director David Simpson. “Now, with scaffolding being removed and the final sections of painting being completed, we’re confident that job will be finished before Christmas.”

After 10 years and an investment of over £130M, the bridge will finally be free of scaffolding. Network Rail said this represents an end to the idiom that “if repairing or improving something is like painting the Forth Bridge, it takes such a long time that by the time you have finished doing it, you have to start again”.

  • Interesting to derive from the "Facts" in the article, that if the bridge was solid masonry, over it's entire length from foundation to top, it would be nearly 300km wide! And since when has area been measured in km³?

    Can NCE please pay a little more attention to getting their facts right?

  • Dear John, thank you for highlighting the conversion error on the painting area. The figure has now been corrected to 230,000m².

  • Dear Editor

    My first comment relates to the volume of "Concrete and masonry in piers"- do you have the correct figure for that?

  • John, the correct figure for that is 91,746m³ -- the same m to km conversion error was made for both. Please accept our apologies.
