Tower Bridge - $3.50
The bridge consists of two towers which are tied together at the upper level by means of two horizontal walkways which are designed to withstand the horizontal forces exerted by the suspended sections of the bridge on the landward sides of the towers. The vertical component of the forces in the suspended sections and the vertical reactions of the two walkways are carried by the two robust towers.

This is our largest one sheet model and it comes out to be just about Z scale. To enlarge it to even just N scale we had to make up THREE pages. Pretty nice model and it could be enlarged to HO with a photocopier, I'm sure. It's been re-colored beautifully with PhotoShop.
Let us know what you think of it.
