Chiverton Cross • Island Shop Interchange • Twelvewoods Roundabout

A double mini roundabout at the junction of the A39 and the A390. One of the directions (marked for St Austell at the junction), leads onto the Truro City Centre bypass and this creates a multiplex between the two roads, with the A39 turning left off the A390 after Truro. Arch Hill is the name of the road in the Falmouth direction.

History

Arch Hill was the first double mini-roundabout in the UK and was used by the Road Research Labs to make sure that this kind of junction could work. This lead onto the creation of the Magic Roundabouts of Swindon and Hemel Hempstead, as well as other places. It was built as part of the Truro Relief Road in the 1970's and has remained virtually untouched during this time, although recent plans may change this.
