The bridge was built using a top-down method, including bored piles, 60T precast pile caps, double hollow-core deck spans, and a reinforced in-situ topping slab.
Construction occurred in a high-traffic urban environment, requiring detailed traffic management and staged sequencing to allow live traffic operations. Retaining walls included 1,500m² of interlocking concrete crib walls, timber walls up to 2.7m, and a 200m² MSE Keystone wall. The site’s natural watercourse required strict environmental controls and proximity to a historic cemetery involved archaeological and Iwi coordination.
