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.

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?

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

Joining the M1 at J6a.
The widest sliproad in the world?
Leaving the M25 at J21 for the M1.

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.
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.
Catenary lighting with Phosco P415 lanterns along the M1 at the M25 interchange near Watford.
Urbis Sapphire lanterns along the M1 at the M25 interchange near Watford. These have since been replaced and switched to LED, using Phosco 860 lanterns.
