The B3300 is a short road linking Redruth with the north coast.
Route: Pennance - Redruth - Portreath
The road starts from the southern suburbs of Redruth, called Pennance, at a roundabout junction with the A393. The first part of the route is actually a re-numbered A393. That route was given a new alignment on a beefed-up Sandy Lane which leads to the east of the town. The wide single carriageway approach to Redruth of the past has been narrowed with build-outs, hatching and the like.
Ahead is a five-way traffic-light-controlled junction. Left turn is the B3297 which heads off to Helston, right is a one-way street away from the junction and not under light control and the remaining right and left forks are an unclassified route to the town centre and the continuance of this route. Both these forks were the original A393.
Continuing on Falmouth Road, the B3300 passes rows of small terraced houses before going under the railway viaduct and reaching another traffic light, this being for a simple three-way junction with the unclassified Station Hill. Continuing ahead another light is reached. This is where historically the A393 ended at its junction with the A30 and the B3300 actually started ahead. Redruth has had two bypasses since then and now the right turn is not possible as it's a pedestrian zone and the left turn is unclassified, although still marked for Camborne.
Continuing ahead, some small shops and a disused industrial building are passed and after Chapel Street becomes Tolgus Hill a roundabout is reached. This was built chiefly for the superstore which is the left turn. The second and third exits are both the B3300. The second exit goes to link up with the dualled A3047 and which is the first of Redruth’s bypasses built in 1939 and again a former A30. The right fork goes under the A3047 which is on an embankment. This is a really old example of a GSJ. The southbound route under the A3047 has been made cycle only and other vehicles have to divert onto the A3047 at another short link road, the junction for which is now reached.
The link road would have been the other half of the grade separated junction, but now acts also as a diversion route and the A3047 now has a roundabout installed for diverted traffic to turn right onto it and leave by the other half of the junction.
The road then gets its first taste of the NSL and then immediately passes under the second Redruth bypass built in 1975 and now the route of the A30, which is on a high viaduct at this point. There are some houses and industrial units which are passed and then the old Tolgus Tine Mine which has been turned into a family attraction called Treasure Park.
It's then into open countryside but that doesn't last long. There is a mobile home park and industrial units on the right and then the hamlet of Bridge. It's a 40 mph limit along this whole section even when the buildings disappear and the trees start. Presently the outreaches of Portreath are entered. There is a 20 mph limit for the community school and there are humps. Those end at Portreath proper but then the road just gives up at The Square, bending left and becoming the B3301 instead.
