Project information

The construction of the new Windsor Bridge is now complete and was opened to traffic in May 2020. The final traffic configurations was completed in December 2020.

Final utility relocations was completed in December 2020 and the commissioning of the lighting on Thompson Square is currently being done and will be completed by early July 2021.

Non-Aboriginal archaeological objects discovered during the project were handed over as part of the project approval and the Heritage Interpretation Plan to the Hawkesbury City Council and are now part of the Hawkesbury Museum’s collection. Archaeologists will continue to work in the project area when required.

The Hawkesbury City Council has a number of archaeological items currently displayed at the UNCOVERED exhibition at the Hawkesbury Regional Museum. The online Thompson Square website showcases these and the many other archaeological discoveries and tells the story of the tens of thousands of years of human history uncovered during the bridge project.
