The Scheme includes approximately 6.6 km online widening and approximately 6 km of new offline highway. The existing carriageway would be widened on its current line up to Priest’s Bridge, from where the proposed offline section of the Scheme would move west of the current road and pass west of Tindale Hill and Causey Park Bridge. Just north of Burgham Park, it would re-join the line of the existing carriageway and widening would continue along the existing road northwards, until it meets the existing dual carriageway north of Felton.
A new bridge over the River Coquet is proposed in parallel to the existing bridge. Three grade separated junctions are proposed, at Highlaws, Fenrother and West Moor. Two accesses would be closed, at Bywell shooting grounds and Low Espley, with new accesses / new local roads provided to the new junctions. Some minor roads would be diverted to join the new dual carriageway at the new junctions.
A new parallel road will link the existing A1 with Westmoor junction. This will provide local traffic with an unbroken link between the Fenrother and Westmoor junctions. The current A1 will be de-trunked and retained as a local road between Priests Bridge and Felmoor Park to allow access to the villages and properties along the route.
