|Route outline (key)|
Our route begins at traffic lights on the A256, 200 m northwest of that road's Townwall Street junction with the A20, and immediately begins climbing the steep tree-lined hill past Dover Castle using that old trick – sharp bends – to reach the summit. The site of this 12th-century castle is also home to a vast network of Second World War tunnels, a Saxon church, and a Roman lighthouse built in 46 AD.
After some open fields, we reach the roundabout with the A2 (which has taken a less winding and faster route from Dover) and continue straight ahead. This next section of road now has a 50 limit, which is strange as it seems devoid of habitation!
The pleasant village of St Margaret's at Cliffe (which has two lighthouses) is nearby, but we continue to Ringwould. There is a tree-lined dip before this village which merges seamlessly into Walmer and (after we meet the B2056 and come within sight of the sea) Deal.
There is a gentle descent to the seafront of this town which, in terms of population, is surprisingly as large as Dover. We pass Henry the Eighth's typically round castle and enter a brief one way system, TOTSOing right and then left to run along the seafront (note the lengthy pier).
Having bypassed Deal's High Street, we TOTSO left again at a roundabout and cross the railway as we leave the town. We meet the B2056 again in Upper Deal before reaching open country. There are a couple of hamlets to punctuate the flat run to Sandwich. A more interesting route from Deal to Sandwich is a toll road via Sandwich Bay golf course – the British Open has been played here.
On the southern edge of Sandwich we reach a roundabout and turn left which leads us out to the A256 bypass where the A258 ends. However, it is well worth a detour to the right for a look around this ancient and compact little town with its narrow bridge over the River Stour.
The A258 originally ended on the then-A256 Dover Road just south of Sandwich town centre, and appears to have survived the construction of the Sandwich Bypass in 1981 by some years.
