Significance in Design 

Written by Christopher Finigan

On my first day in Massachusetts, my mother and I drove to Lowell from Boston, and after driving across the Aiken Street Bridge, we drove across the Central Bridge. As we were crossing, I noticed that there are Pratt truss variations in addition to the Warren characteristics. This bridge may well be a Warren truss. However, it could possibly be a Warren/Pratt truss hybrid or at least a Warren truss with Pratt characteristics. It would be great to know for certain.
