Pavement slab subsidence, major surface cracking and surface roughness.Concrete road pavement slab repairs and asphalt re-sheeting to rehabilitate pavement, improve ride safety and extend the life of the asset.
Road seal has degraded due to its age and use, requiring reconstruction and resealing.Continue to reconstruct and reseal bitumen road. The works were not able to be fully completed in the previous year due to cost escalation and scope.Total cost of proposed project is $120,000
The road requires a full pavement rehabilitation and widening due to the observed width and shape issues, reconstruction of the wearing surface due to the aging spray seal giving lessor traction as well as no longer providing adequate water proofing. The significant amount of interaction seen between heavy vehicles and commuter/tourist traffic causing road geometry/width upgrades to be a much-required safety improvement. There are also significant stormwater issues adjacent the Seppeltsfield Winery due to the lack of formal stormwater infrastructure. Stormwater is seen to run along the edge of the seal causing additional damage, pond in poorly graded sections and ultimately spill into private property in the more extreme events. The formalisation of stormwater management, through the inclusion of kerb and pipes etc. is critical through this sectionThe proposed project works include pavement rehabilitation/reconstruction including localised road widening. Kerb and gutter reconstruction in areas. Local Area Traffic Management devices to manage the contrast between speed and road dimensions to promote a safer road environment. The pavement rehabilitation/reconstruction is proposed to include pavement thickening to accommodate the current traffic loadings and those anticipated in conjunction with the approved developments of the Seppeltsfield Winery, including heavy vehicle movements. The typical desired cross-section for the upgrade is proposed to include: 3.5 m wide lanes with 2 m wide shoulders (1 m sealed, 1 m unsealed) in each direction, or on-street parking and kerb and gutter, where applicable adjacent Seppeltsfield Winery as is existing. The preliminary pavement design indicating a pavement thickness with a thin bituminous surface of between 440 and 470 mm and a 40 mm asphalt wearing surface is proposed. The desired road widening, to the full desired width will prove challenging in some areas of this proposed section of Seppeltsfield Road, due to the State Heritage Date Palms lining Seppeltsfield Road. As such, in these width limited areas the use of Local Area Traffic Management devices is proposed, promoting a lower speed environment. Allowing the utilisation of 3.0 m wide traffic lanes. It is also proposed to request the Department for Infrastructure and Transport to approve the lower posted speed limit in these areas to 50 km/hr. The inclusion of formal stormwater management infrastructure, such as kerb and gutter is also proposed to be installed in areas of high flow rates and limited existing infrastructure.Total cost of proposed project is $2,100,000
Koolunga Road was constructed over 20 plus years ago and sealed 7m wide to accommodate the vehicles of the day. Access by road trains has resulted in significant edge break damage encroaching up to 300mm into the travel lanes. Significant rutting is also occurring in the outer wheel path causing stormwater to pool and creating a hazard for motorist. Council is incurring significant costs yearly undertaking repairs and fighting a losing battle to maintain the width of the sealed surface. The road is a critical community access route linking the townships of Koolunga and Brinkworth, where many children from Koolunga attend the preschool located at the Brinkworth Primary School. It is also a significant tourist route, popular with Gray Nomads following the old broad-gauge rail lines and traversing to the Flinders Rangers. Many of these visitors stay at the RV site located within Brinkworth. The road currently carries an average of 260 vpd during the peak harvest season at an average of 54 heavy vehicles and 190vpd outside of the peak period.The work proposed includes stabilisation 3m wide, 150mm deep on each side of Koolunga Road from the centre of the travel lane. The seal will be widened from the existing 7m to 8.5m by applying a two coat 14/7mm C170 spray seal on the 5.05km section of Koolunga Road from the end of the kerb and water table at the Brinkworth township heading north to Boucaut Road. Line marking will include centre and edge lines to help prevent heavy vehicles from straying off the sealed surface.Total cost of proposed project is $810,000
The road pavement has insufficient thickness. There is a rutting – pavement interactive. The road requires full pavement reconstruction due to its narrow width, heavy vehicle loading, failed pavement and seal, poor road, and shoulder drainage. The road is in an 80km hour zone and has a large amount of intersection between heavy vehicles and commuter vehicles with the widening of the road and shoulders improving safety.The work proposed includes widening and reconstructing the whole section of Magazine Road with a pavement that is suitable for long term (future projections with growth) heavy vehicle loading of adequate width and shoulders/clear zones. The road surface suffers from heavy rutting and poor drainage. All road requires full reconstruction. The overall carriageway width will be increased from 6m to 8.6m with pavement to be surfaced to a thicker from 300mm to 335mm.Total cost of proposed project is $1,796,000

The main carriageway is of med-high standard, but the shoulders are in poor condition. The increased seal width will eliminate edge erosion ultimately reducing shoulder drop off and greatly reduce the potential of vehicles losing control and to improve the safety for heavy vehicle as this now major route for heavy vehicles.The proposed works on Balumbah/Kinnaird Road will include widening of the carriage way by undertaking profiling and shoulder reconstruction between Plane Road / Balumba Kinnaird intersection to Kielpa/Gum flat Road/Balumbah Kinnaird intersection. This will greatly improve the safety along as this is now major route for heavy vehiclesTotal cost of proposed project is $800,000
The resealing of the sections of Range Road, between Tapanappa Road and Parawa Road, has been identified as a priority in condition modelling undertaken as part of the District Council of Yankalilla’s transport asset management process. The nature and use of Range Road and the age of the seal makes it a high priority renewal project. Over the past five years Council has been required to undertake significant patching works on failing pavements along an 800m section of road, resulting in extended period where Council has had to implement temporary traffic controls to allow for safe use of Range Road. Previous PBS Level 2A Detailed Heavy Vehicle Route Assessment undertaken by HDS as part of the South Coast Freight Corridor scoping works, identifies the requirement for shoulder construction and widening for the for the length of range Road. In accordance with PBS Guidelines a 3.1m traffic lane width and 1.2m shoulder shall be provided for roads classified for PBS L2. For Range Road, between Tappanappa and Parawa road, there are large segments with poor edge condition and severely degraded or no established road shoulders. There are also areas where the shoulder has significantly degraded such that edge break of the seal is encroaching on the travelling lanes. Shoulder establishment, pavement renewal and resealing of Range Road will ensure that these segments of road will meet PBS Level 2A requirements.Full depth pavement reconstruction for 830m of road between Tunkalilla Road and Illawong Road. current Australian Standards. Establishment, reinstatement, and reconstruction of road shoulders from Tappanappa Road to Parawa road to provide a minimum 0.5m Sealed shoulder and 1.0m unsealed shoulder for the length of this project.
