 A bypass for Brighton and Hove, rerouting the A27 trunk road away from inner suburban areas, was first discussed in the 1920s, but the borough and county councils only voted in favour of one in 1980–81.A route looping tightly around the northern boundary of the Mile Oak estate and the rest of the urban area was chosen.Hove Council insisted that the road must run entirely to the north of Mile Oak, rather than passing through it; this pushed the route further north and added engineering complexity, and the Department for Transport stated in 1982 that the budget would have to increase by £5.75 million to accommodate this change.
