I would agree that his figure of 20Bn seems woefully inadequate. Looking close to home, the Queensferry Crossing was 1.7 miles and cost 1.3Bn (including roadworks on each side). That was without any of the particular issues that the Boris Bridge would come with such as Beaufort's Dyke munition issues, depth of water (the QC was only 40-50m to bedrock) etc.
