Abergeldie’s innovative methodology was adopted by the client. This included delivering the bridge during limited shutdown periods from one side of the river and using a 200 tonne crane to install the arch, with a temporary jacked-up barge in the River for support. This method eliminated constraints and issues of working over water and removed the need for temporary headstock construction in the river and later removal. The crane also allowed the bridge to be installed over the tops of existing mangrove trees on the banks, minimising impacts on the sensitive riverside environment.

Our innovative construction methodology enabled the Sydney Ferry service to operate continuously on the River, except for a short shutdown period.

Both sides of the Parramatta River feature high-rise residential buildings. Works were delivered in daytime only hours and a high level of prefabricated steel components (including the diagonal arch and steel supports) and coordinated daytime transport delivery helped to minimise the impact on local roads and noise levels for residents.

The Alfred Street Bridge provides a direct connection over the river to the Parramatta Light Rail stop on the southern side, along with services, schools and recreational opportunities.

The completed Alred Street Bridge is Australia's first true diagonal bridge and provides for even more of the community to enjoy over 20km of off-road paths along the Parramatta River.
