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 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 two-lane Springfield extension, including interchanges at Garden Road, Progress Road, the Logan Motorway, and Springfield Parkway, was completed by 2001, since it is shown in that year’s Brisbane UBD. ==Extension==
