The A283 is a medium-length A-road in southeast England.
Milford – Shoreham by Sea
The road begins to the north of Milford at a dumbbell GSJ on the A3 bypass. It runs south into town, crossing the A3100 (pre-bypass A3) at adjacent sets of traffic lights and then the A286 at a roundabout. The A286 to the east here is the original northern end of the A283.
The A283 as it descends through Fittleworth Common towards Fittleworth
Leaving town, we go almost due south to Wormley where the road starts to wind, although it continues in a vaguely southerly direction. Presently we reach Petworth, where we cross and briefly multiplex with the A272, then head south-east through the village of Fittleworth. The road crosses the River Arun at the historic Stopham Bridge, though uses a new bridge these days. The A283 crosses the non-primary A29 at Pulborough, very briefly multiplexing between two mini-roundabouts. The A283 now gets ever closer to the South Downs. It runs east, south, then east again to pass through the small and busy town of Storrington, after which it crosses the A24 at a roundabout at Washington, at the very foot of the South Downs.
Here, the A283 becomes a primary route and passes below Chanctonbury Ring on the ridge of the South Downs. It continues along the foot of the Downs and passes between the delightful villages of Steying and Bramber, though it used to pass through both of them. The A283 then meets the A2037 from Henfield at a roundabout and turns south down the Adur Valley through the Downs. It crosses the A27 at the unusual Shoreham interchange and loses its primary status before terminating at its junction with the A259 coast road in Shoreham itself.
A283, Steyning bypass
The A283 has seen a few upgrades over the years, most notably the bypass of Steyning and Bramber, with the old road running through the villages. Part of the Steyning bypass is built on the old Shoreham to Horsham railway line, hence the deep cutting here.
The bridge at Stopham is also not original, and at Washington the road used to pass through the village and briefly multiplex with the A24 before the A24 bypass was built.
Before the building of the Shoreham bypass, the A283 crossed (and briefly multiplexed with) the A27 at the end of a narrow toll bridge where the A27 crossed the River Adur.
