The balanced cantilever and incremental launching girder bridges link the coastal villages of Coalcliff and Clifton and carry two lanes of traffic, and a pedestrian walkway.

The Sea Cliff Bridge replaced a section of Lawrence Hargrave Drive that was permanently closed in August 2003 due to regular rock falls.

Completed in 2005, the Sea Cliff Bridge structure comprises a haunched box girder composed of prestressed concrete that was constructed using the balanced cantilever method, with five spans.

The bridges were officially opened by the NSW Premier Morris Iemma on 11 December 2005, and were met with public approval and increased business for the area's tourism industry.
