Built in 1972 at a cost of £28 million, evidence of corrosion became apparent after two years of operation.
By 1989, £45 million had been spent on repair.
By 2010 it is estimated that a further £120 million will be spent on repair.
Estimated first cost of installing stainless steel reinforcement in critical locations — £3.4 million (i.e. a 12% increase in the initial cost of the via duct).
The total cost of repair of the carbon steel reinforcement till the year 2010 would be £45 plus a further £120 million = £165 million or nearly six times the original cost of building the viaduct. For a 40-year service life of the viaduct, the price to be paid for not using stainless steel rebar.
