A391

Route

The A391 is a reasonably short A-road in central Cornwall.

St Austell - Innis Downs Roundabout

New course for the A391

Just to the east of St Austell on the A390, the A391 strikes northwards away from the coast. The initial section runs close to the edge of St Austell but never quite gets that close, though a series of roundabouts give access to the town. We climb steadily as we bypass St Austell, then as we leave the fringe of the town, we turn northwards and run on the crest between two quarries towards Penwithick. I believe the quarries provided clay but I might be mistaken. We then turn left, the B3374 taking the straight ahead route through Penwithick. At Stenalees we reach a roundabout where we cannon with the B3274, again passing more quarries on the way.

This first part of the A391 is not the original route - that can be seen by following the southern part of the B3274 from the centre of St Austell to Stenalees.

We run on a good straight alignment past even more quarries to the village of Bugle. A left turn at the traffic lights in the village takes you to Roche Rock where you can see the remains of an old chapel and hermit's cell on top of a quartz rock. But this is off our road, so you'll need to retrace your path back to Bugle to remain on the A391.

After passing over a railway, we leave Bugle and head north towards Lanivet, where we reach a roundabout on the A30. The A391 once followed the minor road to end on the A30 at Lower Woon but the arrival of the A30 bypass obviously changed that. The A391 now terminates at the A30 Innis Downs roundabout, the onward route to Bodmin being the A389.
