-The southbound bridge has 2,246 spans (decks).  Each span is typically 28’ in width by 56’ in length.  Southbound was completed in 1956.

-The northbound bridge has 1,506 spans.  Each span is typically 28’ in width by 84’ length.  Northbound was completed in 1969.

-The spans consist of monolithically-cast, precast prestressed concrete girders, decks and rails.

-The spans are supported on precast pile bents resting on top of 54” diameter hollow, precast, post-tensioned concrete piles.  The southbound pile bents have two piles each and northbound have three piles each (to support longer span length).  Over 9,000 piles support the bridges.  Piles average 90’ in length.
