Longbridge Island is junction 15 of the M40.
Construction started in 2008 to create a bypass on the A46, avoiding the main roundabout. The eastern end of the bypass will be fully grade separated, while an extra roundabout is being created at the western end.
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.
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.
