A27 Arundel Bypass

Scheme outline

Construction of a bypass to carry the A27 past Arundel. There is already a bypass for the A27, but it is now quite old and runs very close to the town centre. The A27 presently reduces from dual to single carriageway approaching the town from both the east and west, and negotiates several junctions that regularly suffer congestion. The objective of this scheme is to allow the A27 to flow past Arundel as an uninterrupted dual two-lane expressway.

At present there is no route for the bypass and Highways England are consulting on possible options, though they appear to have ruled out an on-line upgrade of the existing road. This means that the scheme will almost certainly involve construction of a bypass on a new line to the south of the town.

Highways England may be in trouble with their present proposals for this new bypass as they seem to be unaware of an eccentric demand made forty years ago. In the 1970s, the Duke of Norfolk reluctantly agreed to release some of his land for the construction of a southern bypass for Arundel, but made it an absolute condition that the new road would be called a "relief road" and not a bypass. He was insistent that, if the scheme were referred to as a bypass, Arundel would not get one. He also made it a condition that, once the new bypass was built, the existing one running close to the town must be returned to open land. At present there are no plans for that to happen.

Whether or not these conditions still apply is unclear, and the present Duke is not the one who set out those conditions in the 1970s.
