|Route outline (key)|
The A3047 starts at the slip roads from/to the A30 at the beginning of the 1975 Redruth bypass. The junction is limited access, as there is no entry onto the A30 westbound from here. The eastbound on/off slips have a roundabout junction and a bridge across and then have to give-way to the westbound exit slip, which is partially two-way to allow access to a pub.
We join the route of the old A30 and pass caravan and truck dealerships on either side of the road. It's then under a railway bridge and a small roundabout junction with the B3298 is reached. This is the re-designated A390, which was diverted at Threemilestone to run to the A30 at Chiverton Cross. The road has a semi-rural feel and a 40 mph speed limit.
Another small roundabout is reached and the A3047 forks right, with the left fork becoming the A393. The road then takes the original Redruth bypass which opened in 1939 as the A30. It climbs to cross the railway line again and then opens out into a dual carriageway. It gains a 50 mph limit at this point. There is a roundabout junction with an industrial estate before a large junction with the 1975 A30 bypass. This is a double roundabout, with the grade-separated roundabout above the new A30 being added right beside the 1939 vintage one that used to serve just local access. There are very short connecting roads between the two and the local access that was the right turn involves a traverse of the two roundabouts.
The road sweeps downhill to another roundabout for access to the B3300. This is a newer addition. The original grade-separated junction had a tunnel under the then-A30 which has now been made one-way northbound for the B3300 and has a cycle lane southbound. So those travelling south on the B3300 must divert onto the old eastbound onslip, use the roundabout and then exit at the other half of the junction to the west. In addition, a man-made chicane narrows the westbound carriageway to one lane. This is to prevent weaving as after the chicane the left-hand lane exits onto the other half of the B3300. This is followed immediately by another chicane and exit for a school. The westbound route then gets its two lanes back to take it down to a roundabout and the end of the 1939 bypass and dual carriageway.
It's back onto the 1922 route of the A30 now and a much more built-up environment plus a 30 mph limit. Or at least, there used to be. The 30 limit remains, but within half a mile, just before a set of traffic lights, the route now heads off to the left. Until 2015, this was an unclassified road but the A3047 has been routed over it so that it avoids Pool and Tuckingmill along the Camborne-Pool-Redruth Link Road. We quickly reach a roundabout for the Barncoose Community Hospital and we head straight on into an industrial estate. The road hasn't been resurfaced since it has been built and the road is littered with potholes. This will hopefully change soon though.
After a couple of miles driving through the industrial estate, we reach a new roundabout which has been built for the Camborne-Pool-Redruth Link Road. We turn left and head towards the railway and squeeze in between the railway and Carn Brea Leisure Centre. We reach a new junction with the road from Four Lanes and we continue past Tesco Extra to the traffic lights at Heartland. Until 2015, you could only head straight on here. This takes you to East Hill traffic lights (and the old A3047) and continue past Cornwall College to reach the A30 at Tolvaddon Interchange.
These days, you can turn left onto a partially developer-funded new road which runs through the former South Crofty Mines site, over the Red River Valley up to Dolcoath Roundabout. Turning right takes you onto Dolcoath Road, and left takes you to Brea and the Brea Tunnel. We head straight on to reach the developer built section of road, which is rubbish compared to the new section. The less said about it the better. There is a new set of traffic lights for Tesco on the outside of the development and then we reach the roundabout originally built by Tesco, which has been made smaller. We head left to rejoin the former route.
At the junction with the B3303 the A3047 has been made one-way eastbound through Camborne's main shopping street, Trelowarren Street. Travelling westward it is necessary to follow the B3303 for 500 m before turning right onto the unclassified Cross Street, and then Commercial Street, in order to rejoin the A3047 at a left turn into Church Street in front of Tyacks Hotel: a far from intuitive route for anyone unfamiliar with the town!
The road continues through town, negotiating a mini roundabout and pedestrian crossing before, at Trewithian, it turns right at a roundabout, leaving the old 1922 route – which continues (now declassified) ahead – in order to reach a fourth, and final, link with the A30: a diamond interchange at the end of the 1975 bypass.
The 1939 bypass, numbered then as A30 and which subsequently became part of this route, was actually built partly on an existing route, numbered B3299. That is the current-single carriageway part that crosses the railway line at the Scorrier end.
Once the 1939 bypass had opened, the A3047 number was given to the old A30 right through the town centre. This can be traced from the roundabout junction with the current A393 and taking that route to Sandy Lane and then the right fork off the A393 along East End; Higher Fore Street; Fore Street; across the junction with the B3300 at Penryn Street; along West End and out of town on the other side on Blowinghouse Hill to the current roundabout junction with the A3047 where the 1939 bypass ends. You will no longer be able to do that in a vehicle though, as Higher Fore Street and part of Fore Street are now one-way eastbound and the other part of Fore Street is completely pedestrianised.
The 1975 second Redruth bypass led to the route being extended at either end to Scorrier and through Camborne.
The Camborne–Pool–Redruth Link Road led the the route moving from Tuckingmill and Pool. At Barncoose, by the traffic lights, it bared right to continue into Pool to reach a double mini-roundabout. It headed straight up the hill, past the retail park and another mini roundabout before reaching the spur towards Tolvaddon, then straight back down East Hill into Tuckingmill where it passed between lots of former mining cottages as it weaved up the other side through artificial chicanes. It rejoined the new route at the former Tesco Roundabout.
