The A29 is a traditional main road in England in Surrey and chiefly in West Sussex that runs for 34.3 miles (55.2 km).
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.

The A29 is a major road in Northern Ireland; it is mostly a single carriageway and goes through a number of main towns and connects in several places to other major roads.
The road begins in the town of Portrush, heading south for a few miles before becoming the ring road around Coleraine. The road includes a short section of dual carriageway between Lodge Road Roundabout and Greenmount as part of the shared route with the A37 (north) where it runs west towards Limavady. At a roundabout built in 2005, just outside Macosquin, the A37 continues west while the A29 heads south towards Garvagh.
After Garvagh, the road goes through Swatragh, Maghera, Tobermore, Desertmartin and Moneymore. It then becomes Dual Carriageway as far as Cookstown, goes through Cookstown and onto Dungannon as single-carriageway the rest of its journey via Armagh, Keady, Newtownhamilton and Drumbilla, County Louth in the Republic of Ireland where it joins the R177.
