Design and construction of Dean Street Bridge, Albury

Sinclair Knight Merz was engaged by Abigroup in 2005 to undertake the road and infrastructure design of the Albury-Wodonga Hume Freeway Project for the Roads and Traffic Authority of NSW. The 17.4km section of road links the Hume Freeway at Wodonga with the existing Hume Highway at Ettamogah. The brief for SKM's Sydney Bridge Group included the detailed design of seventeen road, pedestrian and railway bridges of which one bridge in particular was to be a statement structure for the City of Albury. This was a 134m long pedestrian bridge which spans across the Great Southern Railway Lines and the new Hume Freeway to link Dean Street with the East Albury Cycleway, thereby linking the Albury CBD with the community on the eastern side of the Freeway. The bridge has two 67m spans with a central pier between the rail and freeway corridors. Given the span lengths of the bridge and the intention to create a landmark structure at the eastern end of the main street of Albury it was agreed with the RTA during the post-tender discussions that the pedestrian bridge should be a cable stayed structure. The design included the provision of: a span configuration to accommodate the site topography, foundation materials and design constraints for the rail and freeway corridors; aesthetic qualities consistent with an iconic structure; close liaison with Abigroup to achieve a detailed erection procedure satisfying all design, constructability, and risk issues; investigation of the dynamic response of the cable-stayed structure to vertical and lateral pedestrian excitation employing non-linear transient dynamic analyses on Strand7 software in accordance with AS5100.2 guidelines; a construction sequencing analysis using Strand7, with independent confirmation using Microstran.
