This is the Crossroads Section, pre-painted, cast in flexible resin (as described in detail in our previous article). It's listed as 28mm and 1:56 scale, 12cm square.
Let's add the Cobblestone Road, Small, which is 20cm long and about 7cm across. (There's also a double-length piece available.)
Let's add a curved road section. This one is so new, it's not in their online catalog yet. 22cm across.
And let's add an S-curve section (also not in the catalog yet). About 23cm across.
Lastly, here is the bent road section added. 12.6cm across.
To give a sense of scale, here are my 28mm Soviets hitting the road…
Or if you prefer, Survivor Steve at the crossroads, ready for the zombies to come!
