       Land. They've stopped making it.   

       Spiral ramps are going to have a huge footprint.

       If you look at the site from above, there's not much space on the land approaches to construct anything - it's pretty built up already.   

       The photo distorts the perspective - seen side-on it's nowhere near as steep as it looks.
