Tumblong Deviation Hume Highway Nsw (Dec 1983)

Tumblong Devia1ion, located approximately midway between Sydney and Melbourne, will provide 17 km of high—standard, dual carriageway highway linking the township of Tumblong and the intersection of the Hume Highway and 1he Snowy Mountains Highway. A significant illus1rat ion of activities within the Aus1ralian Bicentennial Road Development Programme funded by the Australian Government, this project will bypass one of the best—known but least loved sections of the existing Hume Highway — Sylvia’s Gap. The first 11-km section, which was opened to traffic in November 1983, will be followed by the remaining section in the first half of 1984. The completed section has been constructed by White Industries Ltd and Leighton Contractors Pty Ltd for the Department of Main Roads NSW. This work represents the longest section of slipform road construction to be opened in Australia and is the first occasion on which an entire 11.6-m carriageway has been paved in a single pass. This article provides a summary of the pavement design and construction.
