Windsor Bridge spans the Hawkesbury River, New South Wales from the town of Windsor on the southern bank to the farmlands of Freemans Reach on the northern side. After crossing the bridge, the main road follows the riverbank to the town of Wilberforce. Adjacent to the bridge is also the Freemans Reach Road which leads through the farms to the village of Freemans Reach.
Windsor Bridge over the Hawkesbury River was opened on 20 August 1874 at a length of 455 feet with 11 bays. The deck was raised by 8 feet in 1897 and other improvements were made in 1924.
In 2020, the old bridge was replaced by a new, slightly higher concrete structure.
