Looks like this road next to the railway has progressed slightly in that there is now a tarmacked pavement.
I actually walked along this section today as there were no workmen about to say "Oi - you are not supposed to walk along here yet!"
I was a bit suspicious about that green thing half way along, but this looks like it could be some sort of electricity substation for the proposed new development bordering this road.
This picture was taken from the railway footbridge which gives a good view of the area.
At the end of this unmade section it reverts to a "finished" section of road, but as it does not go anywhere yet there is little traffic, although I have seen some vehicles use it only to have to turn round when they realise it just leads to a construction site.
