It carries Newbridge Road, the continuation of Canterbury Rd/Milperra Rd from Bankstown into Liverpool. HistoryPrior to the bridge being built, there was no crossing of the Georges River between Moorebank and Milperra, though the road to Canterbury was built up to the east bank. The road over the Liverpool Weir and its later 1894 truss bridge went south east toward Wollongong and Engadine. There was call for access between the two military settler camps, Moorebank and Milperra, to have access and a punt was proposed in the early 1920s.[1] The early design by the Main Roads Dept showed a height above water of only 12 ft[2] which was much decried by the locals, advising to the Dept that it be higher for the commercial and sporting interests of the area. The Dept replied with a proposal of 17 ft.[3] After long use, the old narrow bridge was not able to cope with the increase in traffic and was slated for replacement.[4] The current concrete structure supersedes the earlier truss bridge built circa 1930[5] as a wider and higher crossing of the river. {{Infobox bridge| name = composite truss version (1930) | native_name = | native_name_lang = | image = | image_upright = | alt = | caption = | coordinates = {{Coord|-33.929441|150.978890|format=dms}} | os_grid_reference = | carries = Newbridge Road | crosses = Georges River | locale = | official_name = | other_name = Moorebank Bridge[6] | named_for = | owner = Department of Main Roads | maint = | heritage = | id = | id_type = | website = | preceded = | followed = | design = composite truss | material = wood | material1 = | material2 = | length = {{convert|237|feet}} | width = {{convert|20|ft}}[7] | height = | depth = | traversable = | towpath = | mainspan = {{convert|90|ft}} | number_spans = 6 | piers_in_water = 5 | load = | clearance_above = | clearance_below = {{convert|17|ft}} | lanes = | life = | num_track = | track_gauge = | structure_gauge = | electrification = | architect = | designer = | contracted_designer = | winner = | engineering = | builder = | fabricator = | begin = | complete = | cost = | open = 18 April 1931[8] | inaugurated = | rebuilt = | collapsed = 1965 | closed = | replaces = | replaced_by = current bridge | traffic = | map_type = | map_relief = | map_dot_label = | map_image = | map_size = | map_alt = | map_caption = }} References1. ^{{cite news |url=http://nla.gov.au/nla.news-article103317534 |title=MEETING AT CHIPPING NORTON. |newspaper=The Cumberland Argus and Fruitgrowers' Advocate |volume=XXXVI, |issue=2890 |location=New South Wales, Australia |date=2 December 1922 |page=5 |via=National Library of Australia}} {{Bridges in Sydney}}{{Road infrastructure in Sydney}}2. ^{{cite news |url=http://nla.gov.au/nla.news-article104722245 |title=TOO LOW |newspaper=The Cumberland Argus and Fruitgrowers' Advocate |volume=XL, |issue=3576 |location=New South Wales, Australia |date=2 September 1929 |page=1 |via=National Library of Australia}} 3. ^{{cite news |url=http://nla.gov.au/nla.news-article76315979 |title=Will Block Launches |newspaper=The Biz |location=New South Wales, Australia |date=30 August 1929 |page=7 |via=National Library of Australia}} 4. ^{{cite news |url=http://nla.gov.au/nla.news-article189957509 |title="Bottleneck" bridge to go |newspaper=The Biz |issue=2943 |location=New South Wales, Australia |date=14 November 1962 |page=2 |via=National Library of Australia}} 5. ^{{cite news |url=http://trove.nla.gov.au/newspaper/article/16629783?searchTerm=Milperra |title=Advertising |newspaper=The Sydney Morning Herald |issue=28,753 |location=New South Wales, Australia |date=1 March 1930 |page=22 |via=National Library of Australia}} {{cite news |url=http://nla.gov.au/nla.news-article76319538 |title=MILPERRA BRIDGE. |newspaper=The Biz |location=New South Wales, Australia |date=28 March 1930 |page=1 |via=National Library of Australia}} 6. ^{{cite news |url=http://nla.gov.au/nla.news-article76324392 |title=NEW GEORGES RIVER BRIDGE |newspaper=The Biz |location=New South Wales, Australia |date=21 November 1930 |page=6 |via=National Library of Australia}} 7. ^{{cite news |url=http://nla.gov.au/nla.news-article76317024 |title=Advertising |newspaper=The Biz |location=New South Wales, Australia |date=1 November 1929 |page=5 |via=National Library of Australia}} 8. ^{{cite news |url=http://nla.gov.au/nla.news-article16769962 |title=NEW BRIDGE |newspaper=The Sydney Morning Herald |issue=29,105 |date=17 April 1931 |page=12 |via=National Library of Australia}} 1 : Road bridges in New South Wales |
