It is about time they did something about the A406. It is absolutely
ridiculous that such a strategic trunk road linking east/north/west London
has so many bottlenecks, resulting in absurdly long journey times and frayed
nerves.

Some sections are OK (up to 5 lanes each way with underpasses and slip
roads) but other sections have just one lane each way and traffic lights at
busy junctions.

It is long overdue.

The frustrating thing is that most of the ground work has been done;
houses have been bought and demolished and in the case of the Bounds
Green - Green Lanes stretch there are already extra bridge 'arches' for
the extra lanes to go.

The main problem is Henlys Corner, especially westbound. To have 2 major
road merge in and out like that is just ridiculous. either side is dual
carriageway, surely even a basic 4 lane flyover would relieve things
immensely.
