Anzac Highway Underpass

How is construction being managed?

Preliminary works on the site began in early 2007, with major construction taking place from August 2007. The underpass is expected to open to traffic in late 2009.

Noise walls along the western side of the new road will be constructed as early as possible to reduce impacts to the occupants of neighbouring properties. Property owners and tenants affected by traffic access restrictions/noise treatments are being consulted in advance of any major works occurring.

Preliminary construction activities included the placing of additional culverts under South Road at Brown Hill Creek and services relocation, mainly occur to the west of the current South Road alignment.

Details of the construction activities and how they will be managed are be provided on a regular basis. They can be seen, together with Stage 1 of the Traffic Management Staging Plan in the news section at 'AdelaideConnect’.

Traffic flow on Anzac Highway and South Road will not be significantly affected for most of the duration of the construction of the underpass.

The bridge deck over South Road is scheduled to be built in the first stage of the construction program, between August 2007 and July 2008. It's planned to be built in two stages to allow traffic to continue to flow on Anzac Highway. Temporary traffic lanes will be constructed to divert traffic around the works and to reduce impacts on traffic flow.

Throughout the construction period a major priority will be to keep traffic flowing smoothly along South Road. Two lanes will be operating in both directions at most times during the period of major roadworks, to minimuse disruption to motorists.

Construction activities will generally take place during the day. Any night works will meet the Environmental Protection Authority (EPA) standards to make sure that noise impacts on nearby residents will be minimised. The project team will make sure that all residents and businesses are kept well informed in advance of any night works occurring.
