The A29 at Stane Street, Ockley
|Length:||34.3 mi (55.2 km)|
|North east end:||Capel
| A24 road
|South west end:||Bognor Regis
The road runs from the bypassed outskirts of the village of Capel, south of Dorking, having left the A24, entering West Sussex, passing minor villages and bypassing Billingshurst and crossing Pulborough not on its major axis, crossing the South Downs at Bury Hill and passing Fontwell Park Racecourse before terminating on the A259 at Bognor Regis on the English Channel.
For long distance travel, the route is not a trunk road, as designated by the Highways Agency and as such is of standard road width, often alongside hedges and open fields. Portsmouth and Guildford for example, 15 miles (24 km) and 12 miles (19 km) west of points along the route, are served by the four-to six-lane A3 trunk road.
From Capel to Hardham, south of Pulborough, the road with notable deviations follows the path of one of the multiple Roman roads with the name Stane Street, the Middle English and Old English for Stone Street due to the remaining building materials.
