Below is a bridge that I have been working on. the three pillers for center supports are yet to be completed, but you can get the general idea of what is going on.
There are a variety of different brick styles and various types of molds for manufacture of a variety of pieces. I used a set of curved bridge pieces with the basic set to make the 4 foot bridge. The system also includes molds for doors and window frames. I used Bondo in the molds to make various doors and windows.
I have also found that using concrete coloring agents (made by Quick Crete), you can make brick sections in colors other than grey. I have tried dusting the molds with colored grout to get a varied surface appearance, but have not had good luck thus far.
Jig Stones also contain molds for windows and doors. I use Bondo (you know, that pink stuff that kept your '57 Chevy together with) to mold with. It is easy to use and sets up rather quickly. The parts come out of the molds real easy and can be cleaned up with an hobby knife.
