Description 

This closed bridge over the Ausable River, just above the scenic Ausable Chasm, is a highly unique 2 span pony truss. The bridge itself is already notable for being a pin connected pony truss, built around the turn of the century. However what makes it truly special is that it has a unique feature in that instead of the more conventional approach of the 2 spans being configured as simple ones, a continuous truss was utilized.
