The Sea Cliff Bridge is located south of Sydney on the south coast of New South Wales and forms part of the Grand Pacific Drive which runs 138km from Loftus Royal National Park in south Sydney to Nowra on the south coast. Opened in 2005 as a replacement road for the existing section of dangerous road which ran from Coalcliff to Clifton. The old road was known to be closed due to landslides, cracking and rock falls caused by high rainfall, weak rock and marine erosion.
