Black Dam Roundabout is the roundabout at the north end of the spur from junction 6 of the M3, though the name commonly applies to both junctions.
During 2016, the northern roundabout was majorly reconfigured. The junction was fully signalised and there was an additional road added to the middle of the roundabout that allows traffic from the M3 and A30 westbound to avoid going around the roundabout.
