The Toowoomba Second Range Crossing will be an alternative crossing of the Toowoomba Range for all classes of heavy and super heavy vehicles to improve freight efficiency and driver safety, relieve pressure on Toowoomba and Lockyer Valley roads, and enhance liveability for the city’s residents. The route will be 41km long, running from the Warrego Highway at Helidon Spa to the Gore Highway at Athol.

HDR is responsible for the temporary construction traffic guidance schemes (CTGS) design works for the duration of the construction phase of the project. This includes developing designs from concept through to certified final designs for over 60 CTGSs to date. These CTGSs are all for long term implementation for various earthworks, bridge and retaining wall construction, haul roads, site track/detour routes and access to construction sites.

The prepared CTGSs include a risk assessment to identify any hazards and adequate measurement to mitigate the risk.
