Australia’s performance-based standard (PBS) scheme allowed heavy vehicles to drive along New South Wales’ Kamilaroi Highway in 2022, and now drivers’ routes are set to be further improved with the construction of a 64-metre-long bridge.
The PBS shift to allow heavy vehicles on the highway has saved operators over an hour of time on some routes.
The new Spring Creek Bridge near Narrabri in northern NSW is set to commence in September this year and has been funded to the tune of $13.1 million in a joint venture by the state and federal governments.
A temporary sealed side track will ensure existing two-way traffic flow will be maintained in the area, with the bridge set to be built on the same alignment as the existing culvert.
Minister for Regional Transport and Roads Jenny Aitchson says the new bridge will replace an existing structure that has fallen behind modern road standards.
“The existing Spring Creek Culvert is more than 50 years old and has previously been subject to heavy vehicle restrictions and detours to allow for essential safety work to be carried out to stabilise the structure, creating significant inconvenience for regular users,” Aitchson says.
“The new Spring Creek Bridge will be a stronger, wider structure that meets modern design standards along with current and future road network requirements.
“The new bridge will also improve access for freight and, ultimately, provide greater travel efficiency for all users in the area.”
Although the sealed side track has been constructed on the Kamilaroi Highway ahead of the impeding bridge works, Labor Duty MLC for Baron Stephen Lawrence has warned road-users the track could be subject to flooding and to plan accordingly.
“I congratulate our crews on the completed construction of a side track that will enable traffic to keep moving between Narrabri and Wee Waa during construction of the new Spring Creek Bridge,” Lawrence says.
“I note, though, motorists should be aware the side track may be subject to flooding in case of extreme weather events.
“We have planned for those possible closures with approved detours to be put in place.
“We’re all looking forward to the new safer, wider, more resilient Spring Creek Bridge opening to traffic in late 2025.”
Saunders Civibuild Pty Limited has been confirmed as the successful contractor following a competitive tender process.
