Chybucca Junction

Chybucca is a staggered crossroads between the A30 and B3284, north west of Truro, Cornwall.

It started out as two fork junctions between the two roads. At some point in the 1960's the A30 was subsequently upgraded to a Dual carriageway through the junction, allowing for overtaking and for refuges for turning traffic. This soon became quite dangerous at the junction is used by traffic trying get into Truro and avoid the A390 to the south and because it was one of few overtaking opportunities on the road. The A30 was narrowed to two wide lanes with longer refuges for turning traffic.

Chybucca is due to be the only intermediate junction on the latest A30 Dualling plans, and will provide west facing slips only to the new road at a dumbbell junction. It will also connect to the existing A30 as that will become an Local Access Road, much like some motorways have. During consultation, it was also the only site where an option was given on the routing of the road. The options were to the north or south of the house along the B3284 to the west.
