This is a photograph of Sidcup bypass soon after its opening almost 80 years ago.
So much has happened around this most popular junction it is difficult to believe it ever looked like this.
Today the Sidcup bypass (or A20) crosses the A222 at Frognal Corner and the A224 at Crittall’s Corner. Entering Kent, it runs past Swanley and flows directly on to the M20 motorway.
