I was sent a document last night prepared by Vectos, who are the highways consultants who act on behalf of Sainsbury. The document was intended to inform the review of the impact of any Supermarket on Station Road and, in effect, challenge its viability because of that.
Vectos have given me permission to publish that document on my blog for discussion. It contains some serious issues, including highlighting potential queues of up to 400m on Saturdays at Station Road level crossing. A word of caution - because it is a representative of Sainsbury challenging Tesco - but it seems to be based on factual evidence and, as such, is worthy of debate, which is why I have mentioned it.
The document can be accessed here.
