The A2217 is an urban A-road in south London. Its route is more-or-less east-west.
It starts at traffic lights on the A3 Clapham High Street, opposite Clapham Common tube station and within shouting distance of Clapham Common itself and the start of the A24. It heads southeastwards along Clapham Park Road, then TOTSOs left at traffic lights, keeping the same street name, to head more easterly.
Approaching Camberwell
The A23 is crossed at a signalised crossroads in Brixton after which the A2217 becomes Coldharbour Lane, a name it keeps for the remainder of its route. It soon goes under a railway line and zigzags under three more railway lines soon afterwards at Loughborough Junction. The road then continues northeastwards into Camberwell where it ends at traffic lights on the A215 Denmark Hill.
