Kings Post and Queens Post.

The King's Post bridge is the simplest. A central vertical post with a brace on each side. This bridge can span the length between the bottom of the two post. If you add additional verticle posts with braces on one side ( multiple king's post ) the bridge can span wider creeks. There is a limit when the span becomes to long.

The Queen's Post was designed to span wider creeks. It has two verticle posts that form a box and a diagonal brace on each side of the box. This is a longer span to start and can be made longer with additional 'king posts' balanced on each side of the central box.

As wider streams needed to be spanned various trusses were developed.

Burr Arch - Most common in Parke County. is a multiple King's Post with an arch added. The arch carried additional weight from the center of the span to the outer edges.

The Howe Truss is one form of strengthening a basic truss.
The Long Truss is another form of providing more strength.

The Townsend Lattice is a complete change in how to build a truss. It is a series of parallel braces forming a wall, a lattice . The form is vary strong and can be used for spans at the maximum length of the King's Post and the Queen's Post, but not much longer.
