The bridges link the St George area at Blakehurst to the Sutherland Shire at Sylvania.

Tom Uglys Bridge is one of six major road crossings of Georges River.

The 1929 Pratt truss bridge is listed on the New South Wales State Heritage Register and carries three lanes of northbound vehicular traffic on the Princes Highway.

[7] A new punt capable of carrying 28 vehicles and making the crossing in three minutes was installed in 1922.

[9] By 1929 there were two cable ferries operating, and delays of several hours were experienced on weekends and public holidays.

Following a long campaign by local councils and motoring authorities, a New South Wales Government loan to Sutherland Shire Council was used to finance the replacement of one of the punt services across the Georges River.

The funds borrowed by Sutherland Shire Council were to be repaid by a bridge toll once it was opened.

Notwithstanding the creation of the third lane, by the mid 1960s congestion had grown to a significant level, especially on summer weekend afternoons.

However it was not for another twenty years that funding was allocated by the New South Wales government for the design and construction of a duplicate bridge.
