|Route outline (key)|
The B3285 is a semi-rural B-road in west Cornwall.
The B3285 reappears at a double mini-roundabout then continues in the same direction it was before before turning sharply left and proceeding into Perranporth, the largest settlement in the area. The centre of Perranporth is marked with numerous speed bumps.
At the point where St Piran's Road turns into Boscawen Road the B3285 turns into the B3284, which goes back to the A30. To continue on the B3285 we have to TOTSO right then immediately left - the signs are not at all obvious here.
After passing through this seaside resort the B3285 passes Perranporth Airfield. The road goes slightly inland to avoid the steep Trevellas Combe and then turns sharply right at Barkla Shop before entering St Agnes. There is a one-way system in the centre of town and the B3285 ends here, with the B3277 taking the road out of town.
None of the above was classified in 1922. The original B3285 started on the then-A392 west of Truro at Green Bottom and headed to St Agnes via Three Burrows. The B3285 was extended beyond St Agnes along its current route via Perranporth to Zelah in the 1930s. Then in 1935, the entire original section of B3285 was renumbered B3277, giving the road its current length. The A390 west of Truro has since been upgraded and has taken over the ex-B3285 as far as Three Burrows.
