B3374

Route

Penwithick

The B3374 is a loop off the A391 through industrial south Cornwall.

The road starts at traffic lights in Bugle and heads east out of town along Rosevear Road. We soon enter open country but there are no fields here, just quarries and spoil tips, even if they have been landscaped attractively in places. We go through Rosevear itself and then enter the fields.

Presently the road reaches Carloggas and goes round the bottom of Carloggas Down (which was also quarried) to run through Penwithick. A mini-roundabout is reached on the far side of town and for some years the B3374 ended here on the A391. That road has been slightly rerouted here so the B3374 turns right to end shortly afterwards at a full roundabout.

History

The B3374 reaching St Austell

The B3374 was originally unclassified but gained its number in the late 1920s. However, it was originally significantly longer. As can be seen from the map on the left, the B3374 used to extend south to Mount Charles in St Austell. When the town was bypassed, and the A391 moved eastwards away from the centre, it partially absorbed the B3374's route, so the rest of the road was downgraded. Confusingly, the old A391 became the B3274.
