The Salisbury and Southampton Canal was built from Kimbridge (where it joined the Andover Canal) to Alderbury but was never completed as far as Salisbury; construction stopped at Tunnel Hill, near Alderbury House.
The Bishopstoke-Romsey-Salisbury section of the London and South Western Railway was built north of Alderbury and Whaddon, turning west into the Dean valley towards station at West Dean.
