The junction of main line into the ramps shows
some of my key themes. The visual effect is a
smooth transition from main line with the ramp
structure peeling off. There is only one
structure, not several, a detail that is very rarely
attempted by other designers.
But it is a bifurcation where form follows
function.
My experience of segment fabrication and the
flexibility of the spine and cantilever
construction allows for straightforward
modification of segments to allow a gradual
separation of the carriageway.
