It starts at the terminus of the A5 Centenary Highway at Springfield, and ends at Kenmore where it changes its name to the '''M5''' Western Freeway. It features eight interchanges, the major ones being with the '''M7''' Ipswich Motorway (formerly Metroad 2 / M2) in Darra, the '''M2''' Logan Motorway at Ellen Grove (formerly Metroad 4 / M4), and another at Sinnamon Park. It is the main route from Brisbane to Ipswich, Toowoomba, and Warwick.
In October 2012, it was announced that the planned bikeway from Springfield to the existing bikeway along the Motorway would not proceed. Instead the existing two lane road would be expanded by two lanes.<ref name="baf">{{Cite news |url=http://www.brisbanetimes.com.au/queensland/bikeway-axed-for-centenary-motorway-widening-20121010-27d4n.html |title=Bikeway axed for Centenary Motorway widening |author=Tony Moore |access-date=21 June 2013 |date=10 October 2012 |work=Brisbane Times |publisher=Fairfax Media }}</ref>
==History== Moggill Road to Darra: This section was opened as a two-lane arterial road in 1964. It included a new crossing of the Brisbane River, known as the Centenary Bridge. The first section to be duplicated was from the Western Freeway to a proposed Kenmore Bypass. This was completed in 1984, and included a grade separation at Fig Tree Pocket. The bypass was never built. The Centenary Bridge, and the highway from there to the Mount Ommaney Roundabout, was widened to four lanes in 1987. In 1989, twin bridges over the Mount Ommaney Roundabout, and 1.4km of duplication to the existing Sumners Road interchange was completed. In 1994, the final section from Sumners Road to Ipswich Road at Darra was duplicated. A roundabout interchange was constructed at the latter.
Darra to Springfield: In 1995, a two-lane link road was constructed from the recently opened roundabout at Darra to Progress Road, using parts of Kelliher and Garden Roads. It was later proposed to use this link road as part of an extension of the Centenary Highway to the new master-planned city of Springfield. The section from Progress Road to the Logan Motorway was opened by Minister for Main Roads Steve Bredhauer on 16 December 1998, and the section from the Logan Motorway to Springfield was opened by Premier Peter Beattie on 28 June 2000.
==Extension== A two lane extension of the highway to Yamanto was opened in late June 2009.<ref name="ncho">{{Cite news |url=http://www.brisbanetimes.com.au/national/new-centenary-highway-opens-tomorrow-20090628-d106.html |title=New Centenary Highway opens tomorrow |author=Tony Moore |access-date=21 June 2013 |date=28 June 2009 |work=Brisbane Times |publisher=Fairfax Media }}</ref> The extension cost $366 million and was opened by Anna Bligh. Five bridges along the new section were named after local people, places, events and football teams, including botanist Lloyd Bird and the Box Flat Mine disaster.<ref name="ncho"/> Since this new section contains three roundabouts, it is not motorway standard, and is instead designated as the A5 Centenary Highway.
==Upgrades== ===Duplicate Centenary Bridge=== A project to duplicate the Centenary Bridge commenced construction on 20 April 2023, with a current investment of $298.5 million.<ref>{{cite web |url=https://www.tmr.qld.gov.au/projects/centenary-motorway-ellen-grove-toowong-centenary-bridge |title=Centenary Motorway (Ellen Grove – Toowong), Centenary Bridge, duplicate bridge (known as the Centenary Bridge Upgrade) |publisher=Queensland Government |date=14 February 2024 |access-date=24 January 2025}}</ref>
== Interchanges == The interchange with the Logan Motorway is crossed by a viaduct for the two track railway crossing of the Springfield railway line.<ref name="mslb"/> The crossing is more than 800 metres long and has been designed so that its piers do not obstruct planned upgrades of both roads.<ref name="mslb">{{cite book |title=Multi-Span Large Bridges: International Conference on Multi-Span Large Bridges, 1-3 July 2015, Porto, Portugal |last=Pacheco |first=Pedro |author2=Filipe Magalhaes |year=2015 |publisher=CRC Press |isbn=9781315687193 |page=480 |url=https://play.google.com/store/books/details?id=r8sdCgAAQBAJ |access-date=16 October 2016}}</ref> {{AUSinttop}} {{QLDint |type=incomplete |LGAC=Brisbane |LGAspan=2 |location=Indooroopilly |km=0 |road={{AUshield|QLD|M5|S|33}} Western Freeway (M5) north–east / Moggill Road (State Route 33) north–west{{QLDcity|p=on|Brisbane|Kenmore|Indooroopilly}} |notes=Northern motorway terminus: continues as Western Freeway; northbound exit only to Moggill Road}} {{QLDint |location_special=Indooroopilly–Fig Tree Pocket–Chapel Hill–Kenmore quadripoint |km=2 |road=Fig Tree Pocket Road{{QLDcity|p=on|Fig Tree Pocket}} |notes=Parclo interchange}} {{jctbridge |river=Brisbane River |km=4 |bridge=Centenary Bridge }} {{QLDint |type=incomplete |LGA=Brisbane |LGAspan=8 |location=Jindalee |lspan=2 |km=4.5 |road=Sinnamon Road |notes=Northbound entrance and southbound exit}} {{QLDint |type=incomplete |km=4.7 |km2=5 |road=Seventeen Mile Rocks Road |notes=No northbound entrance}} {{QLDint |location_special=Mount Ommaney–Sinnamon Park boundary |km=6 |road=Dandenong Road west / Glen Ross Road east |notes=Roundabout interchange}} {{QLDint |location_special=Jamboree Heights–Sumner–Darra tripoint |km=7 |road=Sumners Road |notes=}} {{QLDint |type=incomplete |km=8 |location_special=Darra |road={{AUshield|QLD|M7}} Ipswich Motorway (M7){{QLDcity|p=on|Oxley|Brisbane|Ipswich|Toowoomba}} |notes=No northbound exit to M7 westbound; no southbound entrance from M7 eastbound}} {{QLDint |type=incomplete |location=Richlands |lspan=2 |km=9.5 |road={{AUshield|S|30}} Garden Road (State Route 30){{QLDcity|p=on|Richlands|Forest Lake}} |notes=Southbound exit and northbound entrance}} {{QLDint |type=incomplete |km=10 |road={{AUshield|S|30}} Progress Road (State Route 30){{QLDcity|p=on|Wacol|Woodridge}} |notes=Northbound exit and southbound entrance}} {{QLDint |type=incomplete |location=Forest Lake |km=13 |road={{AUshield|QLD|M2}} Logan Motorway (M2){{QLDcity|p=on|Ipswich|Gold Coast|Logan Central}} |notes=No southbound exit to M2 north–westbound; no northbound entrance from M2 south–eastbound}} {{QLDint |LGAC=Ipswich |LGAspan=3 |location_special=Springfield–Springfield Lakes boundary |km=20 |road=Springfield Parkway west / Springfield Lakes Boulevard east |notes=}} {{QLDint |type=incomplete |location_special=Springfield Lakes |km=21 |road=Springfield–Greenbank Arterial{{QLDcity|p=on|Greenbank|Springfield Central}} |notes=Southbound exit only}} {{QLDint |location_special=Springfield Central–Augustine Heights boundary |km=22 |road={{AUshield|QLD|A5}} Centenary Highway (A5) west / Augusta Parkway north / Sinnathamby Boulevard south{{QLDcity|p=on|Warwick|Redbank Plains|Springfield Central}} |notes=Southern motorway terminus: continues as Centenary Highway}} {{Jctbtm|keys=incomplete|conv=off}}
