Birkenhead Bridge Upgrade Works Project

The Project

In 2020, the South Australian Government announced the Birkenhead Bridge Upgrade Works Project.

The $3.73 million State Government funded project will be delivered by the Department for Infrastructure and Transport.

This project is to replace the Birkenhead Bridge timber roadway deck with a Fibre Reinforced Polymer deck, and the eastern timber footpath with an aluminium footpath. Works will also include associated steel protection works, bitumen surfacing and line-marking. These essential works will ensure the bridge’s long term structural integrity and safety for all users. The Birkenhead Bridge is a State Heritage item, which makes works more complex and increases project costs.

COVID-19 Response

The Department will continue to tailor community engagement opportunities in line with the latest COVID-19 advice from health authorities.

Face-to-face engagement opportunities may be restricted and we will continue to be guided by the advice of health authorities, with the health and safety of our stakeholders always our highest priority.

Engagement with community and industry is crucial and we will facilitate information sessions as much as possible to enable face to face engagement.  It is important to assist in managing these events that you register as requested to enable physical distancing as much as possible.


Construction is expected to start on Monday, 3 August and be completed in late 2020, weather permitting. Please click here for more information.
