Re Centenary Highway/Western Freeway situation, I started writing an
article on Wilbur Smith's plans for western Brisbane a few years ago
but never finished it. While incomplete (and there may still be some
inaccuracies), you might find it interesting:
----
In 1959, the year of Queensland’s centenary, work commenced on a
series of new suburbs west of Brisbane. In typical Queensland style,
residents of these new ‘Centenary Suburbs’ were provided with limited
access to the surrounding districts. There was no public transport and
vehicular access was limited to just one road and one river crossing
-- the Centenary Highway and Centenary Bridge. The Centenary Highway
was constructed by Hooker Corporation (the estate developer) in 1964,
providing access to both Moggill Rd at Indooroopilly (via the
Centenary Bridge) and Ipswich Rd at Darra. The highway was a simple
two-way, two lane operation with at-grade intersections at key
locations.
Rapid growth occurred over the ensuing years, placing pressure on the
area’s finely tuned transport network. Brisbane City Council responded
by proposing the construction of an expressway system in its 1961 town
plan. Converging on a Ring Road in the CBD, three radial expressways
were planned to serve key growth centres in the northern, southeastern
and southwestern suburbs. The Southwestern Expressway was to commence
at the Ring Road near Caxton Street in Paddington and terminate at
Moggill, approximately 10 km north-east of Ipswich on the northern
side of the Brisbane River.
Subsequent modelling and testing of the plan by Wilbur Smith &
Associates, an American engineering consultancy, showed that projected
traffic levels on the Southwestern Expressway and 2-lane Centenary
Bridge justified the construction of a much larger freeway network in
the western suburbs. In the recommendations of its 1965 Brisbane
Transportation Study, the firm included the construction of two
freeways and one expressway serving the western suburbs: the Western
Freeway, Centenary Freeway and Southwest Expressway.

Western Freeway
Under the Wilbur Smith Plan, all freeways radiating from the CBD were
to meet at a large ring road around the Brisbane CBD called the
Central Freeway. Similar in routing to Council’s Southwestern
Expressway, the Western Freeway was to commence at the Central Freeway
near Caxton Street and project westerly through the suburbs of
Auchenflower, Toowong, Indooroopilly, Kenmore, Moggill and Pullenvale,
terminating on the southern side of the Brisbane River at Redbank.
Between Indooroopilly and Kenmore, the Western Freeway was to replace
the Centenary Highway. Once completed, the entire facility was to be 8
lanes wide.
Centenary Freeway
The remaining portion of Centenary Highway south of Kenmore was to be
upgraded to a six lane freeway called the Centenary Freeway. The
purpose of this freeway was to provide citybound commuters in the
Centenary Suburbs easy connections to two radial freeways – the
Western Freeway (at Kenmore) and Southwest Expressway (at Darra).
Better links to nearby areas were also included via an upgraded
surface street network.

Construction begins on the Western Freeway
In 1969, a short section of the Western Freeway opened between Milton
Road and Taringa Parade, a narrow residential street that runs
parallel to the freeway near Chapel Hill. This section of freeway,
built by Brisbane City Council in 1968, simply shifted traffic
problems from Taringa’s town centre to Chapel Hill.
Things stayed this way until the late 1970s when construction of an
extension to Moggill Road commenced. It was decided to construct only
the eastbound carriageway of the freeway, providing two eastbound
lanes and one westbound lane on the single carriageway. The idea was
to duplicate the road when demand increased. All bridge structures
were designed with this in mind. Even today, the Waverley Road
overpass in Taringa still carries traffic over vacant land and there
is space at the Moggill Road interchange for an additional
carriageway. The present-day four lane operation was achieved by
widening the super-2 expressway and installing a concrete divider
between the opposing streams of traffic.
Much to the relief of residents on Taringa Parade, the extension to
Moggill Road was completed by 1980. However despite this, there
remained an inconvenient gap between the end of the Western Freeway
and the start of the Centenary Highway. Motorists bound for the
Centenary Suburbs had to pass through a series of intersections on
Moggill Road to reach the Centenary Highway.
Also during this time planning continued for the Toowong-City section
of the Western Freeway. A review of the inner city freeway system was
also conducted resulting in changes to the Western Freeway and the
addition of a second ring route called the Paddington Freeway.
Paddington Freeway was to run from the Western Freeway at Milton to
the Northwest Freeway at Everton Park, allowing traffic to bypass the
Central Freeway and Brisbane’s CBD altogether.
The addition of the Paddington Freeway and the extensive changes to
the central City freeways meant that a four-way interchange connecting
the Central, Western and Paddington Freeways had to be provided near
Park Road in Milton. Several designs were considered including a stack
interchange that was four levels high. In the end, Main Roads
engineers decided on a three-level variant that still would have
provided an impressive gateway to the Brisbane CBD. An advantage of
this new design was that impacts on the historic neighbourhoods of
Petrie Terrace and Normanby would be minimised.

and that's all... for now!
The article doesn't say it yet, but the Centenary Highway was
progressively duplicated and grade separated in the 1980s, with the
gap between the Centenary Highway and Western Freeway being closed in
the late 1980s.
The Kenmore Bypass everyone wants is just the old Western Freeway idea
lifted straight from the Wilbur Smith Plan. Amazing how far we've come
in 50 years... not very far!!!
