Jun 17, Question about Curved Viaduct Kits

Question from Jeff: I'm trying to create a portion of the Glenfinnan viaduct in my layout. I've seen the Faller Curved viaduct kit. Does anyone know if the roadbed that that comes with is detachable? Or does anyone know of another curved viaduct kit for sale, preferably one with smooth concrete instead of bricks? Send in your answer on the Comments Page and I will forward it to Jeff...
