Pavement deformation, shoulder failures and seal failuresStabilise with slag lime, add 100mm of road base, shape and compact, apply two coat seal
There is a narrow bridge at the work location over the Waroona Main Drain. The bridge is of insufficient width to cater for modern traffic and has long been a safety concern to road users.Replacement of the existing bridge with a precast box culvert structure which will allow an adequate and appropriate road width. Reconstruction of some 320 metres of Coronation Road to tie in with the new culvert structure.Total cost of proposed project is $1,269,000
Repeated washing out of two roadway creek crossings. The two locations noted suffer severe washouts during most wet seasons and the severity of the damage is directly related to the magnitude of the wet season.To improve this road's flood resilience by installing two concrete floodways. To date the damage has generally been repaired under the NDRRA program. So additional funding is sort to improve the asset to resist this repeated damage.Total cost of proposed project is $810,177
Pavement and seal failuresStabilise with slag lime, add 150mm of base course, shape and compact and apply 7 metre two coat sealTotal cost of proposed project is $191,708

Sheeted surface has reached end of service life and requires renewal to prevent sub course damage and ensure safe vehicle transport at posted speed limit.Resheet the surface and rectify where needed sub course damage.Total cost of proposed project is $56,400
This Section of Sedan Dip Road is 3km of 6m wide unsealed black soil road. As Sedan Dip Road is an arterial rural road linking McKinlay and Cloncurry Shires, and is subject to heavy stock movements and tourist traffic. This black soil road consistently requires work to address corrugations and during the wet season is subject to washouts and boggy conditions resulting in unsealed sections often being impassable for at least 2 weeks at a time. This segment of road requires sealing to provide all-weather access to the travelling public.Form and seal 3km of 6m wide unsealed black soil road. The starting point for the 3km section of works on Sedan Dip Road to be 29.5km from the Link Road intersection with Sedan Dip Road. Works also to include re-instatement of shoulders, road markers and signage.Total cost of proposed project is $800,000
To address the structural integrity of the road pavement due to soil movement from very reactive soil and there are some drainage concerns. This road has a severe environmental deformation and cracking with moderate load induce cracking. Surface texture has a severe defect. Council's Pavement Management System has indicated that this road is warranted for total road reconstruction.The work will involve a full road reconstruction by total excavation of road base and replacement with a deeper granular pavement to ensure the structure and integrity of the road from possible future soil movement. These work will involve replacing existing kerbs, driveway, traffic control and improving the drainage system. The road pavement being treated is 485m in length and 8m in width.Total cost of proposed project is $363,550
