If you go North/South across the Downs at Hill Barn, Steyning Bostal, Lancing or the cement works, there's a 'road' being built East/West.
The same is going on north of Yapton.
Surely it can't be an actual road cutting through the Downs in spitting distance from the A27.
With you saying it...
What is going up on the Downs?
A massive access road is cutting across north of Worthing/Shoreham.
Does it all link up with the similar road north of Bognor/Littlehampton?
