John Jacob Crew Bradfield, a renowned civil engineer, dedicated most of his work in designing and building the Italian bridge structures. Bradfield acquired several academic certificates from Sydney University. In particular, the prominent civil engineer attained a degree in Bachelor of Engineering and a Masters degree from the same university. During his PhD studies, Bradfield defended his thesis on electric railways and the Sydney Harbor Bridge. As a civil engineer in the department of aviation, he supervised the expansion of the airport to the Alexandra Canal. Professionally, he worked for the Queensland railway and later moved to the South Wales Department.Furthermore, Bradfield specialized in several fields such as designing of bridges, providing a specification for the materials needed, giving a detailed drawing of bridge structures, and supervising the construction operations. As a renowned and consultant engineer in Australia, Bradfield participated in many construction projects such as designing cataracts, dams, and the circular Quarry Railway station. In most cases, his works coincided with the construction of the underground railways. Apart from Bradfield, John Thomas Lang made major contributions in the construction of Italian bridge structures. Lang’s contributions enhanced significant progress in the project. Globally, most people recognize Australia as the top country in green and sustainable building. Moreover, the green building bridge structure in Australia has great impact on the construction and the benefits associated with the environment. The implementation of green building concept increases sustainability through reductions in operational costs, an increase in tenant attraction, and increased return on investment. Honestly, the utilization of high-strength concrete and finely engineered structure could reduce the amount of steel required for the construction. To improve the desired properties of the bridge, engineers should construct a canopy for shade provision and the adoption of double spiral design to reduce the amount of steel needed. Again, to increase sustainability and longevity, craftsmen should have constructed the entire bridge structure with steel.
