Twilight at M25 J21a
The last few minutes of light before it goes completely dark. Many of the lights on the top deck are out so perhaps these MA60's are due for replacement shortly?

The 4 level junction you see is J21 for the M1. For now we head to Enfield then come back here...

M25 @ M1
The four level stack is visible in the distance and the period lighting adds to the charm

The M25 clockwise approaching the M1.
Joining the M1 at J6a.
The widest sliproad in the world?
Leaving the M25 at J21 for the M1.
M1 Motorway at Junction 6a
This is the junction of the M1 Motorway with the M25 Motorway looking north from the Blunts Lane road bridge. The slip roads to left and right are from and to the M25. The current widening works have resulted in one lane of southbound traffic using the outer lane of the northbound carriageway.

The M25 near Junction 21
Welcome to the M25!
Major M-way junction

M25 - now four lanes
Why so complicated?
M1/M25 junction. Note the footbridge nearest to the camera carrying a footpath across the M25. Taken just as works have started on the widening of this stretch of the M25. The extra lane had just been added from the M40 junction to junction 20 when this was taken.
M1 looking south at J6a - On the right above where it says Highways Agency on the sign the lanterns for the catenary lighting are no longer working
M25 Junction with M1
M25 looking anti-clockwise at M1 junction
1970s plan for an alternative Chiswell Interchange using the existing M10 for turning movements between north and east. There are also movements between south and west. The junction is slightly to the north of its current location as what became the M25 uses the existing M10-A405-A6 corridor to reach Bignells Corner.
