Making Viadukt's

[cjallenby]

Back on topic! I built mine using thermalite blocks with an arch cut in them. Three arches was alot of work, but easier than making a mould. After cutting them and placing them they must be rendered to give frost protection.

Off topic again...

Whats your favourite full size viaduct?
