Some Basic Truss Terminology

When is a pony not a horse?

Some terminology has creeped in that may be foreign to some. A Pony truss refers to trusswork that is on each side of the roadway but has no interconnection other than the roadway itself. A Through Truss has overhead members that cross the roadway and add additional regidity to the trusswork.

One way to remember is that you drive through a Through Truss. I don't know how the pony designation originated.
