Portway

• The Portway was a Roman Road from London via Silchester and Old Sarum to Dorchester.
• The modern A30 parallels the Roman route between London, Staines, Silchester and Old Sarum, then departs for Yeovil and Exeter. The A354 appears to follow the Roman route from Old Sarum direct to Dorchester and Weymouth.
