Covered Bridge

I need to span a small ravine between Points F and G on on the map. My original plan was to use a trestle, but since I'll be using a trestle elsewhere, I've decided to add some variety and span this (in true New Hampshire form) with a covered bridge.

My bridge will be modeled after the Cilleyville Bog Bridge, a recently restored historic bridge that's a few miles downstream from the millpond that abuts our property.

This bridge is based on a Town Lattice Truss.
