|Route outline (key)|
The B3287 is a short rural B-road in central Cornwall.
It starts on the A390 at Hewas Water, to the west of St Austell. It then heads southwestwards through the countryside. It has the ignominy of two TOTSO junctions with minor roads and passes no places of note until it enters Tregony after more than three miles. At Tregony, the school is at the top end of the village and a range of speed reduction measures are in place. A 30mph buffer zone outside a 20mph limit, and the area is also guarded with Build-Outs and Speed bumps. The road ends at the far end of the village on the A3078.
Originally the B3287 continued along what is now the A3078 down the Roseland Peninsula to St Mawes, where it ended at the Quay. The road was upgraded in 1935, albeit the classified road was rerouted in St Mawes to avoid Grove Hill.
