B3284 Truro - Perranporth

The B3284 connects Truro to Cornwall's north coast.

The road begins at a roundabout on the A39 Truro city centre bypass. It passes a couple of traffic signals and the Highcross multi-story car park, then, slightly to the east of Truro Cathedral and the main shopping streets, it climbs round a bend and reaches a mini roundabout. It passes under a railway bridge and continues to climb passing the City Inn and narrowing. Truro is Cornwall's only city, but it's still not a large area and the road quickly takes on a suburban feel.

Multi-story Car Park, Truro

The climb continues past a disused garage and the city is then left behind completely and a NSL sign appears. It's a pastoral scene after that, as the route makes the transition from south to north coasts. The rural traverse is interrupted at Shortlanesend, a village which sounds like someone forgot the spaces on the sign. It's a 30mph limit through the village. After that is a good straight section where rapid progress should be possible.

The road then reaches the re-designed Chybucca Junction with the A30. On 24 June 2024, the A30 was fully dualled bewteen Chiverton Cross and Carland Cross and the road now has a dumbell interchange here, so a roundabout either side of the A30 with the road going underneath. The southern roundabout has access to the A30 westbound and is also in the process of having a link to the old A30 built, which will serve as a local access route to Chiverton Cross and places en-route. The northern roundabout has access from the A30 from the west. There are no easterly facing slips either from or to the A30 and traffic is expected to use the aforementioned local access route once it has been re-built. There is access to this LAR to the east from the northern roundabout but it is restricted to local businesses and property owners at present because of construction further along.

Taking the first avialable exit from the northern roundabout and its then 1.3 miles until the A3075 is reached to which our road gives way. This is the Newquay to Chiverton Cross route. A staggered junction is here with a left and right necessary to continue.

Continuing, it's a similar story; a fairly straight B road that crosses the countryside. It drops down a hill into the large seaside village of Perranporth. The last couple of hundred yards are humped and then the road simply becomes the B3285 when that joins from the left at a TOTSO.


The road formely crossed the single carriageway A30 on a LILO junction with a gap in the central reservation of a D1 arrangement. So left then shortly right after a multiplex with the A30. During the A30 dualling works in 2023, that arrangement was replaced with a traffic signal. The section north of the A30 was also closed for a while during these works.
