There are several old routes through Digby. What are now Quarry Lane and Digby Drive both appear on the 1801 drawing for the first edition Ordnance Survey map of Exeter, and are probably much older.
The route of Quarry Lane still exists, from the bottom of East Wonford Hill, past the Heavitree Stone quarries, and east along the Sidmouth Road.
The other old way zigzagged from Salter’s Road to Clyst Road. Woodwater Lane, Digby Drive, the footpath to Baxter Close, and Clyst Halt Avenue to Old Rydon Close still follow the route, although much of it has been erased by Exe Vale Retail Park, the railway, and fields around Sandy Park.
