Scale through truss span bridges custom built to size.

Trough trusses come in many shapes and sizes. They are a simple bridge with box design a divided in to triangles. The lower beam is usually a solid beam holding the weight of the span under load. The longer the span, the heavier the girders used or the taller the truss.

The above is a Santa Fe bridge for a back yard lay out in valley. Below are more shots of through trusses. I would recommend this style of bridge for spans between 20 to 120 inches in G scale. But we can design and build the as large as you need.

We build bridges to look good and last. That’s why we are the better value. Although I will build any size you need.

Standard Sizes Available Are:

28" / 36" / 44" / 52" / 60" / 68" / 76" / 84"

Here is an eight foot Pratt spanning a dry wash.

All sizes are custom fabricated to your dimensions to fit your span needs.

American Scale bridges feature laser cut welded steel construction for very strong and long life indoors and out.
