In 2005, a major upgrade of the Gateway Motorway was announced.<ref name="abc"/> [[Leighton Contractors]] and joint venture partner [[Abigroup]] won the contract to upgrade the motorway. The [[Australian dollar|A$]]1.88&nbsp;billion Gateway Upgrade Project includes the duplication of the Gateway Bridge and upgrades to {{convert|20|km|mi|0|abbr=on}} of the Gateway Motorway from Mt Gravatt-Capalaba Road in the south to Nudgee Road in the north. The bridge duplication was the largest bridge and road development in Queensland's history.<ref name="aus">{{cite web |url=http://www.theaustralian.com.au/news/dual-gateway-opens-brisbane-to-growth-and-prosperity/story-e6frg6oo-1225769697990 |title=Dual Gateway opens Brisbane to growth and prosperity |author=Sean Parnell  |access-date=1 February 2010 |date=5 September 2009 |work=[[The Australian]] |publisher=[[News Limited]] }}</ref> The duplicate bridge was specified to have a design life of 300 years.<ref>{{cite web|last=Hart|first=John|title=NZBridges 2012 – 300-year sustainability: The Second Gateway Bridge Brisbane|url=http://www.conferenz.co.nz/content/whitepapers/2012/300%20year%20sustainability%20-%20The%20Second%20Gateway%20Bridge.pdf|publisher=NZ Bridges 2012|access-date=16 July 2013|url-status=dead|archive-url=https://web.archive.org/web/20130212000009/https://www.conferenz.co.nz/content/whitepapers/2012/300%20year%20sustainability%20-%20The%20Second%20Gateway%20Bridge.pdf|archive-date=12 February 2013}}</ref>

To the south, the upgrade included widening {{convert|12|km|mi|0|abbr=on}} of the Gateway Motorway from 4&nbsp;to&nbsp;6&nbsp;lanes. To the north, it involved the construction of the {{convert|7|km|mi|0|abbr=on}} Gateway Motorway deviation, an entirely new six-lane motorway between the Gateway Bridge and Nudgee Road. The deviation runs east of the original motorway through [[Brisbane Airport Corporation]] land and provides an alternative means of access to [[Brisbane Airport]] (the only effective access from the south). The new bridge provides a bicycle path unlike the first crossing.<ref name="bt1"/>

The Wynnum Road upgrade was completed on 13 July 2007 and 2 additional southbound lanes between the [[Port of Brisbane Motorway]] and Wynnum Road completed in late 2007. Four of six lanes of the new Gateway Motorway deviation were opened in July 2009. All works south of the river were complete by the end of 2009 after 10 years of constant roadwork and traffic disruption. The final concrete pour linking the sides of the new bridge was made in late October 2009.<ref name="bt1"/> A total of 748 concrete segments, which are supported by 17&nbsp;piers, were placed for the new bridge.<ref name="aus"/>

The duplicate bridge was completed in May 2010 along with the remaining lanes of the Gateway Motorway deviation.<ref>{{Cite web|url=https://www.linkt.com.au/brisbane/using-toll-roads/about-brisbane-toll-roads/gateway-motorway|title=Gateway Motorway|website=Linkt Queensland|access-date=2 February 2020|archive-date=9 January 2021|archive-url=https://web.archive.org/web/20210109085037/https://www.linkt.com.au/brisbane/using-toll-roads/about-brisbane-toll-roads/gateway-motorway|url-status=live}}</ref>

In October 2010, then Minister for Main Roads, [[Craig Wallace (politician)|Craig Wallace]], announced that the original course of the Gateway Motorway via Eagle Farm would be renamed to Southern Cross Way, after Sir Charles Kingsford Smith's aircraft, the ''[[Southern Cross (aircraft)|Southern Cross]]'', which landed at Eagle Farm in 1928, and so as to avoid confusion with the newly opened Gateway Motorway deviation.<ref>{{cite web|last=Wallace|first=Craig|title=Southern Cross Way – a legendary name for the Old Gateway Motorway|url=http://statements.qld.gov.au/Statement/Id/72116|publisher=Queensland Government|date=20 October 2010|access-date=1 January 2015|archive-date=9 January 2021|archive-url=https://web.archive.org/web/20210109085040/https://statements.qld.gov.au/Statement/Id/72116|url-status=live}}</ref> The new Gateway Motorway deviation was given the name Gateway Motorway. However, like the renaming of the bridges themselves, the change to Southern Cross Way was not without controversy, attracting criticism from the then Shadow Minister for Main Roads and Transport, [[Fiona Simpson]].<ref>{{cite news|work=The Courier-Mail|publisher=Queensland Newspapers|title=Gateway Motorway name change to Southern Cross Way a 'waste of money', says Fiona Simpson|url=http://www.couriermail.com.au/news/queensland/gateway-motorway-name-change-to-southern-cross-way-a-waste-of-money-says-fiona-simpson/story-e6freoof-1225925184839|date=17 September 2010|access-date=1 January 2015}}</ref>

Refurbishment of the existing bridge was completed in November 2010.<ref name="Queensland Newspapers"/>
