Plus the A1M can be flippin’ slow from Letchworth Gate J9 down to Stevenage South J7. I’ve missed many appointments because of this, despite it being a regular thing 
The M25 will be ■■■ from J22 anti clockwise through the roadworks.
I’d be tempted to go down A505, M1 south, then come off at Bricket wood, round Watford on the A405, and rejoin at J19. But people doing that is what [zb] up the M25 anti clockwise!
Thanks for all the tips. As you can guess I am home again!!!
We left Norwich at 0730 and headed A11, A505, A1, A414. A1 was not too bad. I was going to join the M25 but going over the top at the roundabout I looked down and it was at a standstill so we straight over the roundabout, down the M1, A41, in towards Watford, Bushey, Oxhey, Northwood, Ruislip and over the A40 to Uxbridge.
I’m glad I was stationed in Northwood which gave me the local knowledge. Arrived at friends house at 1035, including a stop for breakfast.
Into court at 12 having just found out the defendant that hit my vehicle wasnt going to turn up. Still had to give evidence and was winding his barrister up as she was putting the incident further round the roundabout. This would have meant that my OSF hit him, which she agreed happened. She wasnt so smug when I told her it was the NSF that was repaired!!
It goes without saying that I won. Including £50 in expenses for both me and the missus. Then a quick shoot off to Datchet Water for an afternoons sail with my trusty crew member.
Thanks again for your help. I also came back the same way as the M25 was blocked near the M10.
