 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.It is an unusual motorway as, citybound, it heads east, southeast after the Anzac Bridge, east, north then northeast.
