Bridges can be purchased as a frame only or as a complete bridge. Complete with decking and or rails.

Sizing

Standard bridge sizes are 4", 6", 8" and 10"

Standard width is 28" to 30", because standard decking material is 5 1/2" wide, the length of a bridge is rounded to the nearest foot.

Example:

6" Bridge = 72" Long divided by 5.5." = 13.09 pieces. Round to the 13-5.5" deck pieces

The arch of the bridge will also slightly reduce the overall length.
