The National Cycleway will have to go along the footpath of the Coast Road. There just is no room to build anything else, although a wooden boardwalk below the sea wall would be brilliant (but expensive). It’s not the most ideal, but we cyclists will put up with it.

A few weeks ago a new walking track appeared about half way along that climbs up the escarpment, and crosses the railroad by going over the hill where the railway is tunneled through. I can verify that the new track isn’t finished yet, and half way up the escarpment it still needs building, and following the route of it was quite scary, in a fall down the face of the escarpment kind of way. Here is looking down on a bit of the Coast Road:
