Phase three was opened by the Secretary of State for Transport Paul Channon on 11 December 1987.
[3] In 2014, the roundabout that formed the junction between the ring road and the A59 was improved by York City Council in time for the 2014 Tour de France Stage 2 to pass over it.
The new roundabout has wider access and exits; improved crossings; new signage and new lighting added.
These include: The south-eastern section (A64) runs as a continuous dual carriageway with grade separated junctions at Grimston Bar (A1079/A166), Fulford (A19) and Askham Bar (A1036).
The north-western section (A1237) is a single carriageway road, and has eleven roundabouts.
