Opponents of plans to buy up land to make the long-awaited Broughton bypass a reality have until July 11 to register an objection to the proposals with Transport Secretary Patrick McLoughlin.
Lancashire County Council chiefs have released a map showing 44 acres of land needed to construct the bypass.
They have drawn up the compulsory purchase orders to acquire land and alter existing roads.
They say all properties needed on the map are either owned by the council or they have reached an agreement with the owners over them.
One pocket of land being snapped up by the council is the car park at Broughton in Amounderness Church of England Primary School and St John Baptist Church – which is believed to be the oldest working building in Preston.
