De Burghs Bridge is a road bridge that carries the Lane Cove Road, part of the A3, across the Lane Cove River in Macquarie Park, Sydney, Australia.

The bridge stretches from Macquarie Park in the south to West Pymble in the north.

The new bridge offers a vantage point to view the remnants of the original structure.

This demonstrates how far road and bridge building had progressed by the 1960s, as previously it was dictated by the form of the land.

De Burghs Bridge is an important part of the A3, a significant north–south artery across metropolitan Sydney which is the next road that connects the northern suburbs and the lower northern suburbs after (to the east of) Pennant Hills Road.
