Aylesford Interchange (also known as Coldharbour) is junction 5 of the M20.
It was first built in 1961 as the terminus of the A20(M). It was laid out as a Trumpet Interchange, but only the roads to and from the east were initially required. Tight, looped sliproads were common on the Maidstone Bypass, an early example of a motorway. The eastbound onslip served East Park Road and Coldharbour Lane, and was actually called Coldharbour Lane itself.
When the road was extended west, the motorway became the M20, with a crossroads to allow access to Coldharbour Lane.
In the mid-1990s the Maidstone Bypass was widened and re-built, and this junction took its present form of a roundabout interchange.
