Provided the bridge concept studies, cost studies
and designs for the 280’ long Approachway bridge (typical
spans 45’) and the two up and down river Accessway bridges
(485’ and 487’ respectively, with typical spans
of 60’) in the Delaware River connecting the new Conoco
Phillips ship dock to their refinery. The study required the
investigation of structural steel beams, precast concrete
beams and precast segmental sections as superstructure alternatives
and two foundation alternatives. The bridge configurations
are prestressed concrete beams with a precast concrete deck
supported on pile bents with composite steel pipe pile/HP
pile foundations.
