Project description

The project involved the upgrade and widening of South Road from Pym Street to approximately 100 metres south of the River Torrens, including a 4 km non-stop section of roadway (which incorporates a 3 kilometre section of lowered motorway) and the grade separation of two major arterial roads (Port Road and Grange Road). Work also included an overpass of the Outer Harbor rail line and improved cycling and pedestrian facilities.

Benefits

The North-South Corridor is a critical route for the movement of freight and business-related passenger traffic, connecting the Port of Adelaide, Adelaide Airport, the Islington intermodal terminal and other freight terminals. Improvements to the corridor contributes to enhanced productivity and increased competitiveness for export industries.

The Torrens Road to River Torrens project addresses one of the highest priority sections of the corridor, providing relief from traffic congestion and improved safety at this critical location. An upgraded South Road will not only improve north-south traffic flows along the corridor, but will also improve connectivity for east-west traffic by reducing delays at South Road intersections.

Funding

The Australian Government has committed $383.5 million towards the $767 million project.

Timetable

Construction began in August 2015 and was completed in late 2018.

The existing road has no gravel and no or incorrect cross falls resulting in erosion, potholes and corrugations.Form sub-grade to correct cross falls, place and compact 100mm of gravel. reform table and cross drains and place guide posts where required.

Sweetman Road, Goolwa South - 059274-15SA-RTR

Poor road surface condition resulting in a majority of the road having surface defects.Reseal road (spray seal) and upgrade surface at intersections to asphalt

Bearbung Road (Rural Road) - 059275-15NSW-RTR

The existing bitumen seal is approximately 25 years old and is starting to break up, causing pavement potholes, shoving of the outer wheel paths and edge break. There is also severe longitudinal and lateral cracking happening. Road shoulders need regrading.Correct any surface defects eg: potholes/shoves, maintenance grade the shoulders, import gravel to reshape shoulders where necessary, then bitumen seal to a width of 6m using 14mm aggregate.

Gilmours Road (Rural Road) - 059276-15NSW-RTR

The existing bitumen seal is approximately 20 years old and is starting to break up, causing pavement potholes, shoving of the outer wheel paths and edge break. There is also severe longitudinal and lateral cracking happening. Road shoulders need shoulder grading.Correct any surface defects eg:potholes/shoves, maintenance grade the shoulders, import gravel to reshape shoulders where necessary, then bitumen seal to a width of 6m using 10 or 14mm aggregate (depending on design).

Seven Mile Road (Rural Road) - 059278-15NSW-RTR

Primary through road formed from natural black material. In wet conditions the road is impassable to all but 4 wheel drive traffic. In dry weather pavement tends to powder up causing deep potholes and rutting.Reshape road and gravel sheet – Win and cart gravel – Spread gravel at 6m wide X 130mm thick, compact to 100mm. Re-establish table and mitre drains.

Waugan St (Gilgandra) - 059279-15NSW-RTR

Primary Town Street that has over the past five years seen this section of pavement deteriorate at a rapid rate, possibly from water inundation originating from the centre island.Investigate any anomalies in the existing road base and correct. Reconstruct pavement, incorporating certified road base material. Bitumen seal, using 10mm aggregate.

Starkies Road (rural road) - 059280-15WA-RTR

Little to know gravel exists on the current road and cross falls are poor or do not exist resulting in erosion along the road, pot holes and corrugations.Form the sub-grade to required cross falls, place and compact 100 millimetres of gravel, clear existing table drains and cross drains and place guide posts where required.

Wrigley Street. (Gilgandra) - 059281-15NSW-RTR

Primary Town Street that was originally formed up with sandy black soil, with the existing seal being in excess of 30 years old.

Reinstate kerb and gutter and storm water inlets (320m). Import certified sub base material, stabilize, form up and compact to a depth of 200mm then import Design Graded Base (DGB) material , form up and compact to a depth of 100mm, trim and shape to conform with new kerb and gutter, then bitumen seal using 10mm aggregate.
