This article is about the current A392 that runs to Newquay.

The A392 is a reasonably short A-road in west Cornwall.

St Columb Road - Newquay

The A392 starts from the Halloon roundabout, which is also the junction of the A39 and a couple of minor roads. It runs in a cutting for a short distance, along a section newly built in 1995, before narrowing as it follows a much older section after the turning for St Columb Road. It then curves left and runs into White Cross, then Mountjoy and then crosses the Newquay branch of the railway and comes to Quintrell Downs. The whole length is a fairly slow road at the best of times, being mostly fairly narrow and with some tightish corners, but in summer is likely to be far slower due to the traffic.

Quintrell Downs

At Quintrell Downs it crosses the A3058 at a roundabout. Left goes to St Austell, right goes into Porth and eastern Newquay. The A392 continues straight on, towards western Newquay. After the village of Lane, it comes to a roundabout called Treloggan but the only turns here are a no-through road and a turn to a small overspill settlement of Newquay and an industrial estate. Continuing ahead another roundabout junction is reached called Trevemper, where the road turns sharply right. Straight on is the A3075 towards Redruth. The A392 curves round, following the River Gannel, to the Mellanvrane Roundabout where the A3058, having come through the middle of Newquay, ends.

The A392 ends at the Mount Wise Roundabout at the western end of Newquay, near Fistral beach, famous for surfing.


The number did not exist in this location until the 1935 numbering revisions and is mostly a re-numbered section of the B3279. This is the part from the St Columb Road turn to Quintrell Downs. The narrowness of the road in this section shows off its B road heritage. The very first section from Halloon, was built in 1995 at the same time as the A30/A39 bypasses of Indian Queens and St Columb Road and it is thus much wider. Previous to that the road went through St Columb Road having started from the A30 in Indian Queens.

In 1935 the road turned right at Quintrell Downs and followed what is now the A3058 (but was renumbered from the B3278) into eastern Newquay and thence through now-unclassified routes in town to the Harbour via the High Street. It was re-routed in the late 1980s along a former unclassified section through Lane to the junction with the A3075, and at the same time took over part of the A3075 to what is now the Mellanvrane Roundabout. The final piece of this new southern Newquay bypass was built along the route of a small lane alongside the Gannel and then between housing to its current terminus at Mount Wise Roundabout. The old road became the A3058.
