Overnight on 2nd August 2008, the Budbrooke Accommodation Bridge on the A48 to the north of the roundabout was demolished, this allows construction to continue on the new GSJ to the west of the site.

October 2009

In October 2009, eastbound traffic on the western side of the junction was diverted onto the new alignment including the new roundabout. Work is underway to remove the old eastbound carriageway to allow the diversion of westbound traffic to the new roundabout.

On the eastern side of the junction, work is nearly complete on constructing the overbridge to take eastbound traffic over the new alignment.
