The London end of the road was built of gravel or small flints over a layer of larger flints or pebbles, about thick at the centre, sometimes on a bed of sand. Route Peckham to Blythe Hill Fields This northernmost alignment branched from Watling Street close to the Old Kent Road in what is now the back garden of Number 77, Asylum Road, in Peckham, running parallel to the road for some distance under other back gardens. Here the road was built of gravel on a base of pebbles. Passing just east of Nunhead railway station the road runs along Ivydale Road, crosses the Crystal Palace Railway, and crosses Brockley Rise at St. Hilda's Church heading to Blythe Hill Fields. Blythe Hill Fields to Titsey On Blythe Hill the road turns 9 degrees to the south, and crosses the River Pool, then turns another 6 degrees southward onto the next main alignment. Here the intact road was found to be made of gravel on pebbles and flints under a golf course. It then crosses the railway about east of Beckenham railway station. Going through Beckenham it passes close to Langley House then east of West Wickham village centre, crosses Corkscrew Hill, and goes down to the Addington to Hayes road, where there was once a small settlement. From Rowdown Woods the Surrey/Kent county boundary follows the road, making a V shaped kink at Skid Hill where the road deviates from the alignment to cross a steep valley. This alignment, marked by tracks and hedgerows, continues to the top of the North Downs above Titsey where it is more than above sea level. Here the road makes a sharp turn eastwards to follow the ridge of the downs, passing south of Tatsfield church before beginning its descent of the escarpment on a terraceway, originally wide, passing west of the rectory, to cross the Pilgrims Way. The road is followed by the Titsey-Tatfield parish boundary for . Titsey to Marlpit Hill south of the Pilgrims Way, at the foot of the escarpment, the road passed a Roman temple where it turned onto the major alignment that goes to Marlpit Hill north of Edenbridge. This alignment was parallel to that north of the downs, but half a mile further east. The M25 motorway cuts across the road south of the temple site, at the end of the eastern slip roads of Clacket Lane
