  • Overall Length : 343,5 m
  • Overall Width : 67,0 m
  • Foundations : Ø 1 829 mm and Ø 1 219 mm cased piles, up to 70 m long with a free height of 22,0 m,  excavated and concreted under polymer.  Berthing forces are resisted through pile flexure.  Reinforced concrete pile caps measuring 2,50 x 2,50 x 0,59 m
  • Superstructure : Composite concrete deck consisting of 1,70 m deep pre-tensioned T-beams, spanning 21 m and weighing 55T acting compositely with a 350 mm thick in-situ deck slab.  There are three 21 m spans, which are partially continuous for dead load.  The T-beams are in turn supported by and monolithically connected to 2,0 m deep pre-tensioned spine beams weighing 60T and spanning 10 m between the piles.  The spine beams rest on the pile caps.  The pile cap to spine beam connection is pinned in a longitudinal direction to allow for settlement differentials and temperature movements, while being rigid transversely in order to allow moment transfer from the deck to the piles for the purposes of resisting berthing forces.
