The A234 is a very short non-primary route in South London - and even this is double its original length: the section west of the A213 was numbered B266 until the 1930s.
Crystal Palace - Beckenham
Crystal Palace Park Road
This road starts from a traffic-light-controlled junction with the A212 very near the giant BBC Crystal Palace transmitter. The road is quite wide and it doesn't feel too urban because of the park on the right hand side of the road. After 1/3 mile there is a pelican crossing. The road descends and after 0.8 of a mile there is a sign on the right for the National Sports Centre. You then go under two railway bridges, the first with viaduct-type arches. The road become Penge High Street and the first shops start to appear. Shortly thereafter there is a 7am to 7pm bus lane on the near side. This lasts no more than a couple of hundred yards. A crossroads is reached where the left and right turns are the A213. Left is marked as 'Sydenham A213 Forest Hill (A2216)'; right is marked as 'Anerley A213 Croydon (A212)'.
We continue straight on marked as 'Beckenham A234 Bromley (A222)'. The shops soon start to peter out and there are mostly Victorian flat conversions on both sides of the road. There is then a light-controlled-junction with a minor road on the left (Kent House Road). We pass under another railway bridge which carries the Beckenham Junction to Victoria (via Crystal Palace) line and the Croydon Tramlink. On the left is Beckenham Road tram stop. Past another railway line and Clock House Station and soon we arrive at the strangely elongated Beckenham War Memorial roundabout where our road ends. Left is the A2015 to Beckenham Junction Station. Straight on is the A222 Beckenham High Road and right is the A222 toward Elmers End.
