Khan said that scrapping the Thames crossing would waste almost £40m of public money already spent. He said £37.7m of the £60m pledged by Transport for London (TfL) and the government had already been spent. If the project was scrapped now, this amount would be lost in full. If built, the Bridge’s Trust would repay a £20m loan from TfL, plus £22m in VAT to the Treasury, meaning taxpayers would have paid £18m towards the scheme.
