The 6.5 BCR is from a New study, of which is still to be made public, this will come in due course, the BBC Report was to highlight that the project had not been included in CP5, which is not an issue, as all the studies haven't been conducted, the project would have to have been just passes GRIP 3, which is a full engineering study, it's at GRIP2 at the minute, about to start GRIP 3, full project cost will not be to hand until this is complete.
The current ARUP 1B/Grip 2 is a desk top study, based on what we know from all the research conducted to date, with current updates in to cost of construction, and other findings.
6.5 is accurate to date, by Arup, using all the latest WebTag formulas, which are still changing, for the better, in regards to the project.
Lancashire CC, have to be the project leaders in this, and so far so good, without them, and North Yorkshire CC backing it the project can't go forward, part of the funding for the GRIP 3 is coming from LCC, and other Local Authorities.
