Editing Isleworth (section)

===Routes===
The principal road in Isleworth is the London Road (A 315), which broadly follows the route of one of the early roads the Romans constructed in Britannia, namely Tamesis Street, built across the wide heathlands ''en route'' to Silchester, from where other roads led to Bath, Winchester and Salisbury.<ref>'And So Make a City Here' by G E Bate F.R.Hist.S. p355 publisher: Thomasons, Hounslow 1948</ref>

As this road from the centre of London passes through Westminster it is called 'Piccadilly' and then 'Knightsbridge'.&nbsp;In Kensington it is 'High Street', in Hammersmith 'King Street', in Chiswick it's the 'High Road', in Brentford it's the 'High Street', and as Isleworth's 'London Road' passes into Hounslow it again becomes 'High Street'.&nbsp;In former times it was part of the 'King's Highway' to Windsor.

A bigger road was completed in 1925, named the Great West Road (A 4), moving in much the same direction and forming the notional northern boundary of Isleworth. A six-lane dual carriageway for most of its length, with attendant cycle paths, it fulfilled the purpose of bypassing the bottlenecks of Brentford and Hounslow high streets to relieve the old road from London of traffic heading to and from Windsor and beyond. A later branch extension off this new road, named the Great South West Road, carried traffic south-westwards and this had the additional effect of relieving the London Road of traffic heading to and from Staines-upon-Thames and beyond.

The other throughway in this category is the Twickenham Road (A 310), which branches off London Road west of the Syon estate and takes traffic to Twickenham, Teddington and beyond. This was the King's Highway to Hampton Court, so in years past those houses fronting on Twickenham Road, such as Somerset House, [[Kendal House]] and the two Silver Halls would have been favoured with a royal gaze from time to time. {{Citation needed|date=January 2017}}
