The detour designs needed to incorporate HOV lanes, cycling lanes, and dedicated bus and truck ramps, and ensure high-speed and low-speed traffic did not mix.
McElhanney successfully value engineered an extradosed segmental bridge concept with 16 back-to-back 120m-long spans for the 1,920m navigation spans portion of the 4km bridge. Approach spans outside the navigation spans utilizes precast segmental erected in span-by-span.
