Terra-City One – Sally 4th's urban/sci-fi Terra-Block range – got a stack of new releases last week to enable raised dual carriageways to be constructed above the urban sprawl. The new stuff includes 5cm x 10 cm pillar sections with three variations plus spreaders, 10cm x 10cm pillar sections and spreaders, and 200mm x 300mm carriageway sections. Using this system, the road sections can be built from 5cm above ground level to any height you like.
