An alternative route description for the A3075 from the Three Burrows end
The road starts at Chiverton Cross which is a roundabout junction with the A30, A390 and B3277. It heads northeastwards, which is the same direction as the A30 eastbound. In fact after a couple of hundred yards, it runs right next to the A30, with only a solitary hedge between the routes. This can be disconcerting to suddenly glimpse a vehicle on the other road.
The roads part and the A3075 follows a mostly straight course through rural Cornwall. The next junction is a staggered one with the B3284, the left turn being first for Perranporth, followed by the right for Truro. Soon is a brown sign for Healey's Cyder Farm (best not consumed before continuing driving). Immediately ahead is the hamlet of Penhallow, in which there is a turning to the amusingly named Ventongimps.
Next is a small village called Perranzabuloe which does have a 40 mph limit, which continues through the bends and narrow road ahead, down a 10% hill and across a stream on a bridge at the bottom. The NSL is restored and continues through the next small place, Perranwell.
Goonhavern is a larger settlement and has a 30 mph speed limit. In the village is another staggered junction, this one which has become seemingly Cornwall’s favourite junction type, the double mini-roundabout. Left is the B3285 towards Perranporth and right is the same road marked for Bodmin via the A30.
The rural outlook and the NSL return and after some further bends the road approaches Rejerrah Hill, a very straight downhill section with a matching straight uphill on the other side of the valley. Known locally as "The Big Dipper", much overtaking is carried out here, but there has also been loss of life because of drivers (and especially motorcyclists) getting carried away.
Following the hill are some primary route (this road isn't one) junction countdown markers for the staggered junction with local roads to Holywell Bay/Newlyn East. It continues for 2 or 3 miles uneventfully before dropping down to the Gannel River and the Trevemper Roundabout, where the primary route A392 terminates the road.
