Junctions related to the A389

This junction opened in July 2007 as part of the wider Goss Moor bypass, a dual carriageway linking the Bodmin and Indian Queens bypasses. The large roundabout here was removed and replaced with 2 smaller roundabouts each side of the A30, resulting in only one bridge needing to be installed instead of 2, no doubt to save on construction costs.


The A30 at Innis Downs before the Bodmin bypass was built

The area has seen several changes over the years. Before the Bodmin bypass was built, the A30 followed the route of what is today's A389. At this point, the A391 joined at a simple at-grade junction.

With the opening of the Bodmin bypass, Innis Downs was a large roundabout that marked the end of the dual carriageway. This section was notorious for massive queues in the summer as most of the traffic at this point would continue on the single carriageway ahead.

For the last few years of the roundabout during the summer months, the Highways Agency would create a diversion system at the roundabout to try and reduce the queues. This involved blocking off sections of the roundabouts meaning that vehicles could only turn left when coming from the A389 and A391 and vehicles on the A30 could go straight ahead or turn left. Vehicles wanting to travel in the opposite direction would be directed down the long bypassed A391 road that went under the A30.
