|The four levels of the Darenth Interchange|
|Dartford, Kent TQ556720|
|3-level stacked roundabout interchange with free-flow links|
|M25, A2, A282|
The junction was built in 1972 when the Second Dartford By-Pass opened. In 1978 the M25 opened southwards towards the Swanley Interchange. In 1991, traffic for Dartford was redirected from M25 J1b to this junction to prevent weaving. Finally in 2008, new slip roads were built for traffic to & fro the North to the A2 east to Dover.
