Every gamer needs bridges for his battlefield. These kits contain the pieces to build up to eight bridges with a total length of over 30 inches. The design is modular so that you can build bridges of different lengths and heights and widths. You could even combine several kits to build very long bridges. The kits also have options like side buttresses and foundation piers. There are three styles available: Brown Stone, Gray Stone, and Concrete. Note: to provide the necessary strength, the kits call for the bridge supports to be glued to cardboard or balsa wood which is not provided.
