A group of local MPs and councillors has been lobbying for this scheme since 2016. They're called the A27 Reference group, and they've only released minutes of their meetings up to 2018, in February 2019, after pressure at public meetings in some of the villages in the paths of the 'corridors'.
With Reference Group prodding, Highways England developed a Strategic Business Case and an Options Analysis, submitted to the Department for Transport at the end of 2018. The Department decided not to fund the scheme in their plans for 2020-25, despite Lewes MP Maria Caulfield describing the case as 'strong'.
Now we await the next move from National Highways, as the Department for Transport has said the scheme could be developed ready for consideration for funding in 2025-2030.
We at SCATE East Sussex have always argued that this road is ill-conceived; the business case has been drawn up in a manner that is more than irregular; the attitude to very serious environmental issues has been frankly cavalier. It will be fought at every stage, until a proper, independent analysis which considers all modes of transport is presented and debated.
