A232 road

The A232 is a road running east–west in two modern counties: across far south London and 3 miles into Surrey. It connects the A24 in Ewell with the A224 Orpington bypass .

Between Croydon and Ewell the road runs close to a northern part of the Sutton & Mole Valley Lines, impliedly from London . Part of the long-distance, express London Buses route X26 runs along the road between Waddon and Cheam. The most common road type of the route is that of a single carriageway, the remainder a neither large nor small minority of its route is a dual carriageway.
