For the first step, measure the distance that the bridge is supposed to span and draw a template that will be used for the walls. Then tape the template to a piece of 1/4" thick foamcore and cut out two copies using a sharp hobby knife.

Next, cut out a 2" wide strip of plasticard that is slightly longer than the width of the bridge walls. Bend the piece of plasticard so that it has a high point in the centre to allow water to run underneath.

Glue the plasticard to the walls using superglue. Make sure that the bridge spans your river and rests neatly in the gap. Some trimming of the foamcore may be necessary to make it fit correctly.

Cover the walls in wood glue and sprinkle them with a fine sand to replicate the texture of stucco. Then cut small pieces of plasticard to represent tiles and glue them on top of the bridge posts and along the sides using superglue.

Make the planks out of strips of balsa wood and glue them to the plasticard using superglue. It's a good idea to nick the corners and the edges of the planks with the hobby knife to make them look irregular and time worn.

We undercoated our bridge with Chaos Black, painted the walls Snakebite Leather and the planks Scorched Brown. Then we drybrushed the walls with Bleached Bone and the planks with Bestial Brown. Increasing amounts of white were added to the mix for each successive highlight. The tiles were then picked out with Scab Red and were highlighted on the edges using Blood Red. We then glued our bridge into place on the river and were ready to play!
