The Barron River bridge near Kuranda, Queensland, is now further restricted to single-lane operation at a 42.5 tonne load limit for all heavy vehicle combinations.
As a precaution, a single-lane operation of the bridge will remain in place to ensure safety for the inspection crew and road users, said the Department for Transport and Main Roads (TMR).
“Inspections are continuing and our technical experts are assessing what the issue means for the bridge and how it can be managed,” said an advisory note to industry from the TMR’s heavy vehicles unit.
Strain gauges and other devices are in place to monitor the structure closely.
“Further changes to the bridge operations may be required, pending the outcomes of the inspections.”
TMR has installed variable message signs (VMS) to inform motorists and truckies about changed traffic conditions and this may add delays to travel.
“The department urges operators to plan your journey ahead or seek an alternative route.”
Post inspections and assessments, an updated bulletin will be shared with the heavy vehicle industry.
“The planning study for a long-term solution for the Barron River bridge is progressing and expected to be completed in late 2024,” the statement added.
For current issued permits and permit applications in assessment, the department said it will review and reassess internally, and the outcome may be subject to change.
