|Junctions related to the A3047|
Treswithian Junction is a modified Diamond Interchange at the western end of the Camborne - Redruth Bypass on the A30.
Built with the Dual carriageway to the east in 1976 as a half diamond, Treswithian formed the western terminus of the bypass until the Polstrong - St Erth Improvement was built and opened in 1983. The west facing sliproads were built at the same time.
The bridge was built at the same time as the junction, leaving provision for the road to be dualled to the west.
It connects to the western end of the A3047 at a roundabout to the south of the junction.
