Angry residents living on the chosen route for Aberdeen's bypass will meet on Friday night to organise a campaign against the road.
They are furious that the Scottish Executive's public consultation options did not include the one chosen.
The bypass is intended to solve growing transport congestion around Aberdeen.
Last month a route was chosen through the affluent Milltimber suburb, instead of the nearby Camphill community for people with learning difficulties.
The bypass could cost up to £395m.
Transport Minister Tavish Scott rejected the five original options in favour of a compromise route through Milltimber Brae, with a new fast link via Netherley to Stonehaven.
The decision was met with shock by Milltimber residents who claim they were not consulted.
They are meeting on Friday with other communities on the chosen route to discuss their next move.
