Bridge Under Construction

I like working with cardboard. As a teenager I made spaceships and a Dalek from Dr Who. With a liberal addition of PVA (wood) glue the end result can be very strong.

For the track I have made a steel girder bridge from layers of cardboard stuck together with, you guessed it, PVA glue.

Much of the track is grey in colour so I have selected red oxide for the bridge to brighten it up a bit. A common paint used on steel work.
