Meinhardt Group provided alignment design, civil engineering pavement, drainage and bulk earthworks design and total structural bridge engineering.

Features of the projects included two 45m spans, four 30m spans and a central span of 70m for Phase IID. The central span of the Phase IID structure was designed to have 17m insitu cantilevers from either side with a 41m drop-in span to enable uninterrupted traffic access across the existing road during construction. The Phase IIC carriageway featured 5 varying length spans between 30m and 40m together with ingress and egress slip roads to and from the expressway.
