The balanced [cantilever](/source/Cantilever_bridge) and [incremental launching](/source/Incremental_launching) [girder bridges](/source/Girder_bridge) link the coastal villages of [Coalcliff](/source/Coalcliff) and [Clifton](/source/Clifton%2C_New_South_Wales) and carry two lanes of traffic, and a [pedestrian](/source/Pedestrian) walkway. The Sea Cliff Bridge was named by Makenzie Russell, who at the time was an eleven-year-old student, following a naming competition opened to local primary school students.[5] The Lawrence Hargrave Drive Bridge and the Lawrence Hargrave Drive are named in honour of [Lawrence Hargrave](/source/Lawrence_Hargrave), an Australian engineer, explorer, astronomer, inventor and aeronautical pioneer. ## History The Sea Cliff Bridge replaced a section of Lawrence Hargrave Drive that was permanently closed in August 2003 due to regular rock falls. A public outcry emerged over the road closure as Lawrence Hargrave Drive is the only road directly linking Coalcliff, [Stanwell Park](/source/Stanwell_Park%2C_New_South_Wales), [Otford](/source/Otford%2C_New_South_Wales) and [Helensburgh](/source/Helensburgh%2C_New_South_Wales) to the northern suburbs of [Wollongong](/source/Wollongong).[6] ## Description The A$52 million 450-metre-long (1,476 ft) bridges brace against the [Tasman Sea](/source/Tasman_Sea), up to 70 metres (230 ft) east of the original alignment of Lawrence Hargrave Drive. Completed in 2005, the Sea Cliff Bridge structure comprises a haunched [box girder](/source/Box_girder) composed of [prestressed concrete](/source/Prestressed_concrete) that was constructed using the balanced cantilever method, with five [spans](/source/Span_(architecture)).[3] Adjoining the Sea Cliff Bridge is the 210-metre-long (689 ft) Lawrence Hargrave Drive Bridge – often not considered as two separate bridges. This latter [girder bridge](/source/Girder_bridge) that was constructed using the [incremental launching](/source/Incremental_launching) method, with seven spans, ranging from 24 to 31 metres (79 to 102 ft), shares a common pier with the Sea Cliff Bridge.[4] The bridges incorporate two traffic lanes of 3.5 to 3.8 metres (11 to 12 ft) and a 2.5-metre (8 ft) pedestrian pathway.[7] Cyclists are allowed to use the traffic lanes and there are shoulders on either side of the road of approximately 1.2 metres (4 ft) width. The bridges were officially opened by the [NSW Premier](/source/Premier_of_New_South_Wales) [Morris Iemma](/source/Morris_Iemma) on 11 December 2005, and were met with public approval and increased business for the area's tourism industry.[6] The bridges sit in a harsh marine environment as it directly faces the open ocean and is affected by high [sea swell](/source/Sea_swell) splashing. It is well attested that concrete structures in such environments are especially susceptible to [chloride](/source/Chloride) induced [corrosion](/source/Corrosion) of the steel reinforcement, which can eventually lead to expensive repair works and significantly decrease the life of the structure.[8][9] ### Tourism An hour south of Sydney, the bridges have been a major tourist spot since they opened in 2005.[10] The area adjacent to the bridges feature a scenic walkway surrounded by rocky cliffs[8] that is a popular location for [love padlocks](/source/Love_padlocks).[11] *Pioneer Walks* published the route to the lookout and encouraged spectators to participate in an "unofficial walk with no safety precautions in place".[12] On 30 September 2018, a 24-year-old man hiked to a lookout on a cliff overlooking the bridges, where the ground beneath him gave way and he slid 20 metres (70 ft) to the cliff’s edge, where he then plummeted 40 metres (130 ft) to his death.[13] Sea Cliff Bridge in May 2020 ## In popular media The Sea Cliff Bridge and adjoining Lawrence Hargrave Drive Bridge were featured in a range of media including: - a joint 2007 [Ferrari](/source/Ferrari)/[Shell](/source/Shell_plc) television advertisement that was shown in Australia and many other countries.[14] - a VE [Holden Commodore](/source/Holden_Commodore) commercial[15] - the video game, *[Forza Horizon 3](/source/Forza_Horizon_3)*, where players can race over the bridge[16] - in [Guy Sebastian](/source/Guy_Sebastian)'s music video for the song '[Choir](/source/Choir_(Guy_Sebastian_song))', where he is seen walking under the Sea Cliff Bridge[17] ## Gallery - Sea Cliff Bridge looking south - The footpath on Sea Cliff Bridge - A photo taken from road level - Looking down onto Sea Cliff Bridge from the south ## See also - [New South Wales portal](https://en.wikipedia.org/wiki/Portal:New_South_Wales) - [Transport portal](https://en.wikipedia.org/wiki/Portal:Transport) - [Engineering portal](https://en.wikipedia.org/wiki/Portal:Engineering) - [Australian roads portal](https://en.wikipedia.org/wiki/Portal:Australian_roads) - [List of bridges in Australia](/source/List_of_bridges_in_Australia) - [Bald Hill](/source/Bald_Hill_(Australia)), a nearby lookout spot ## References 1. **[^](#cite_ref-1)** [$10 million fix for Sea Cliff Bridge](https://web.archive.org/web/20220611084833/https://www.illawarramercury.com.au/story/111864/10-million-fix-for-sea-cliff-bridge/) *[Illawarra Mercury](/source/Illawarra_Mercury)* 10 July 2012 1. **[^](#cite_ref-SCB_Stats_2-0)** ["Bridge Construction Statistics"](https://web.archive.org/web/20090912125201/http://seacliffbridge.com/scbstatistics.html). *Sea Cliff Bridge*.
