Toowoomba Second Range Crossing - constructing the viaduct by Isaac Kirsch

Abstract

The $1.6 billion Toowoomba Bypass, formerly referred to as the Toowoomba Second Range Crossing (TSRC), is a 41 kilometre heavy vehicle route jointly funded by the Australian and Queensland Governments under a Public Private Partnership with Nexus Infrastructure. The route is designed to increase freight efficiency and improve driver safety and community amenity by removing a significant number of heavy vehicles from Toowoomba’s CBD. The completed Bypass connects the Warrego Highway at Helidon Spa in the east to the Gore Highway at Athol in the west via Charlton. The TSRC creates a safer, faster and more efficient route for connecting freight to major ports and markets. Figure 1: Location of Toowoomba Second Range Crossing and the Viaduct. The project features: • four lanes (two each way) from Warrego Highway east interchange at Helidon Spa, to Warrego Highway west interchange at Charlton • two lanes (one each way) from Warrego Highway west at Charlton to Gore Highway at Athol
