Baluarte Bridge saddles in the pylons to form 152 suspenders in a two plane semi-fan layout. The tallest intermediate pier, P9, is high. It crosses a gorge in the Sierra Madre Occidental mountains with a clearance of below the deck, substantially taller than the Eiffel Tower. Its clearance is higher than that of the previous record-holder, France's Millau Viaduct, which has a clearance of .
