Hi group.
I might well have occasion to drive from the bottom of the M1 to
Brixton in the fairly near future, and at least one way will be during
charging hours, which means either a lengthy detour or the free route.

Has anyone on here driven the north-south free route yet? How well
signed is it? Any pitfalls for the unwary driver-ie how easy is it to
accidentally drive into the zone, especially after dark?

Or is it all very simple?
