History

Pyrmont-darling-harbour-western-distributor-construction-early-eighties

The Western Distributor came to be out of the realisation in the early 1960s that the existing roads that supported the Harbour Bridge would not cope with contemporary and projected traffic volumes. Due to existing infrastructure and buildings in the area, it was decided to build a viaduct to carry traffic above the city streets. Western Distributor - Construction Information"

Abandoned section

Under the Western Distributor viaduct ramps at its northern end, between Sussex and Kent streets, there is an abandoned carriageway underneath the main roadway. It is a short section of elevated freeway; the top tier remains in constant use but the lower is suspended in the air; having been severed at each end.

Route

It is an unusual motorway as, citybound, it heads east, southeast after the Anzac Bridge, east, north then northeast. The freeway distributes traffic arriving from the north (a function which gives the road its name) while collecting traffic from the CBD, distributing it through Pyrmont and Ultimo before crossing over the Anzac Bridge. In the citybound direction, traffic is collected from Victoria Road and the City West Link, as well as various on ramps in the Pyrmont and Ultimo areas. Traffic is distributed into the CBD through various off ramps in Pyrmont and the western edge of the CBD, as well as into the

. The remaining traffic is fed into the Bradfield Highway, as it is not possible for northbound traffic to exit onto the Cahill Expressway (traffic travelling east on the Western Distributor wishing to reach the eastern edge of the CBD and beyond must either travel through the Cross City Tunnel or negotiate the packed streets of the CBD).

, as that was where the North West Freeway was intended to finish, however due to protests from inner city residents, this plan never came to fruition. The Western Distributor ends west of the Anzac Bridge western ramp and east of the junction between Victoria Road and City West Link, with traffic fed onto either of these roads. Construction of the Rozelle Interchange as part of Stage 3 of WestConnex is underway. With its scheduled completion in 2023, it will provide traffic-light free access from Sydney's CBD to its outer western suburbs and the Blue Mountains.
