Description

The scheme is an integral part of National Highways commitment to deliver a high-performing, high-quality route along the A303/A358 corridor between the South West and South East. It will also help to conserve, reconnect and enhance the Stonehenge world heritage site (WHS), making it easier to reach and explore, as well as improving biodiversity and providing a positive legacy for nearby communities. 
The scheme will be approximately 8 miles (13km) long and comprises the following key components: 
* A northern bypass of Winterbourne Stoke with a viaduct over the River Till valley;
* A new junction between the A303 and A360 to the west of and outside the WHS, replacing the existing Longbarrow roundabout;
* a twin-bore tunnel approximately 2 miles (3.3km) long through the WHS; and 
* a new junction between the A303 and A345 at the existing Countess roundabout.
