Covered Bridge

I need to span a small ravine running thru the back hill.

I've decided to 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.
