There has to be a smarter way of ending the dual carriageway bit of West Hill than this: https://goo.gl/maps/t3CiPp3M4RB2
Well indeed. The TfL route network is full of things that ought to have been revised 20 or more years ago, but have just been habitually repainted in what provisional manner was laid out in the 60s.

The only way I can see for this to change would be to trunk the major roads in London, handing them back to Highways England...
Given that the direction of travel with the railways is the opposite - with more routes, to outside of London - being handed over to TfL, I suspect handing roads back is unlikely. Even if HE wanted them!

I drive J10-16 regularly, and took a good look at the option the other day for D5 between J10 and J12. As others say above, between 10 and 11 this would be hugely expensive and disruptive to build, what with the long elevated section at Byfleet including bridges over railway and river. There’s also 2 transmission pylons immediately adjacent to the carriageway which would require relocating.

The only viable long term solution is to build the M31. This would relieve J10-15 of all traffic from the channel ports and points south of London, heading to the southwest, Bristol and South Wales. Given that we seem to be tentatively thinking about more ambitious tunnelling schemes, the M31 could be constructed with a tunnelled section under Horsell/Woking which is the main sticking point for the route.
