In 2020, National Highways (formerly Highways England) announced the preferred route for the A27 Arundel bypass. This will replace the existing single carriageway road with a dual carriageway bypass, linking together the two existing dual carriageway sections of the road.
The new bypass will feature approximately 8km of dual two-lane carriageway to the south of the existing A27. Starting at Crossbush, the route will reconnect with the existing A27 in the west near the A27/A29 Fontwell (east) roundabout.
Key features will likely include:
- a junction at Crossbush with access to and from the A27 in both directions
- a new viaduct spanning the River Arun and a bridge over the Arun Valley Railway
- a new bridge over Binsted Rife
- a new junction with the existing A27 at Tye Lane to the north of Walberton (with the A27 continuing via an underpass) enabling westbound access onto the A27 and eastbound access from the A27
- the closure of Tye Lane south of the new route.
Subject to the agreement of the County Council (as local highway authority) the existing A27, approximately 6.6km in length, will be ‘detrunked’ and converted to a local road between the junctions with Tye Lane and Mill Road and Crossbush junction.
National Highways will consult on the draft proposal from 11 January to 8 March 2022. Information about the project, including the latest news about its development, is available on National Highways' website.
The County Council’s formal response to the consultation will be approved in April 2022.
The broad timetable for the project is submission of the Development Consent Order (DCO) application in summer 2022, followed by examination through to mid-2023 and a decision by the end of 2023. If consent is awarded, construction would not start until 2024/25.
