At the present time the City of Edinburgh Council is negotiating with some of the landowners for parcels of land in order to carry out the planned upgrade of the junction. It is intended to include a right filter to turn up Dalmahoy Road, a right filter to enter Dalmahoy Country Club and a pedestrian crossing all controlled by 4 way traffic signals, along with realigning pavements and re-siting bus stops.
