The A307 Portsmouth Road running through Thames Ditton.
|Length:||13.2 mi (21.2 km)|
| A205 road
|Richmond, Kingston upon Thames|
The A307 road is a 13.2 miles (21.2 km) road runs through SW London and NW Surrey. It is primary at the north-east end but for the most part is a non-primary A-Road which has been superseded by the new alignments of the Portsmouth Road.
Richmond Upon Thames
It begins at the junction with the A205 South Circular Road beside Kew Green (, where it is named Kew Road. It then runs towards )Richmond upon Thames or Richmond, London, through the west of Kew. At the junction with the A316 in Richmond it becomes a non-primary A-road through the town centre then heads through Petersham where it for fewer than 100 metres kinks west and then travels south through Ham. A B-class road, the B353, leaves the A307 in Kew and runs around the town centre and up Richmond Hill and by-passing Richmond, before rejoining the A307 at Petersham.
Kingston Upon Thames
It bisects the north of the town before becoming the western half of the one-way system in Kingston upon Thames. Here it is briefly merged with the A308. It leads south to the northern end of the A240, for 200m travels west to the River Thames, and resuming south becomes at last the old version of the Portsmouth Road (which is also its name here). It runs next to the River Thames, heading through Surbiton. It passes a junction with the A243, shortly before exiting the borough at Seething Wells there next to Long Ditton.
The Thames which is curved alongside Thames Ditton veers away from its now almost straight south-west course; the road passes through Hinchley Wood, going through the Scilly Isles roundabout with the A309. It forms the High Street of Esher, crosses the A3 (new Portsmouth Road) by way of a bridge north of Cobham, before terminating near a junction of the A3 in Cobham ( which is generally also known as Portsmouth Road. ),

The A307 follows the old route of the Portsmouth Road, particularly the section south of the junction with the A308. Since the invention of the motorway, the Portsmouth Road, now the A3 (Portsmouth Road), has been diverted away from towns to be routed through buffer land which instead of forming the centres of settlements is typically approximately 1 mile (1.6 km) or more from these and is a tripled or dualled road in each direction.
In more recent times, nearby, the A307 was notably disrupted during 1979–80 when it was closed for almost 18 months by the collapse of a sewer in its narrow section in Petersham, popularly referred to as the Petersham Hole.
